-# Nominatim contribution guidelines
-
-## Reporting Bugs
-
-Bugs can be reported at https://github.com/openstreetmap/Nominatim/issues.
-Please always open a separate issue for each problem. In particular, do
-not add your bugs to closed issues. They may looks similar to you but
-often are completely different from the maintainer's point of view.
-
-## Workflow for Pull Requests
-
-We love to get pull requests from you. We operate the "Fork & Pull" model
-explained at
-
-https://help.github.com/articles/using-pull-requests
-
-You should fork the project into your own repo, create a topic branch
-there and then make one or more pull requests back to the openstreetmap repository.
-Your pull requests will then be reviewed and discussed. Please be aware
-that you are responsible for your pull requests. You should be prepared
-to get change requests because as the maintainers we have to make sure
-that your contribution fits well with the rest of the code. Please make
-sure that you have time to react to these comments and amend the code or
-engage in a conversion. Do not expect that others will pick up your code,
-it will almost never happen.
-
-Please open a separate pull request for each issue you want to address.
-Don't mix multiple changes. In particular, don't mix style cleanups with
-feature pull requests. If you plan to make larger changes, please open
-an issue first or comment on the appropriate issue already existing so
-that duplicate work can be avoided.
-
-## Coding style
-
-Nominatim historically hasn't followed a particular coding style but we
-are in process of consolidating the style. The following rules apply:
-
- * Python code uses the official Python style
- * indentation
-   * SQL use 2 spaces
-   * all other file types use 4 spaces
-   * [BSD style](https://en.wikipedia.org/wiki/Indent_style#Allman_style) for braces
- * spaces
-   * spaces before and after equal signs and operators
-   * no trailing spaces
-   * no spaces after opening and before closing bracket
-   * leave out space between a function name and bracket
-     but add one between control statement(if, while, etc.) and bracket
- * for PHP variables use CamelCase with a prefixing letter indicating the type
-   (i - integer, f - float, a - array, s - string, o - object)
-
-The coding style is enforced with PHPCS and pylint. It can be tested with:
-
-```
-phpcs --report-width=120 --colors .
-pylint3 --extension-pkg-whitelist=osmium nominatim
-```
-
-## Testing
-
-Before submitting a pull request make sure that the tests pass:
-
-```
-  cd build
-  make test
-```
-
-## Releases
-
-Nominatim follows semantic versioning. Major releases are done for large changes
-that require (or at least strongly recommend) a reimport of the databases.
-Minor releases can usually be applied to exisiting databases Patch releases
-contain bug fixes only and are released from a separate branch where the
-relevant changes are cherry-picked from the master branch.
-
-Checklist for releases:
-
-* [ ] increase version in `nominatim/version.py` and CMakeLists.txt
-* [ ] update `ChangeLog` (copy information from patch releases from release branch)
-* [ ] complete `docs/admin/Migration.md`
-* [ ] update EOL dates in `SECURITY.md`
-* [ ] commit and make sure CI tests pass
-* [ ] test migration
-  * download, build and import previous version
-  * migrate using master version
-  * run updates using master version
-* [ ] prepare tarball:
-  * `git clone --recursive https://github.com/osm-search/Nominatim` (switch to right branch!)
-  * `rm -r .git* osm2pgsql/.git*`
-  * copy country data into `data/`
-  * add version to base directory and package
-* [ ] upload tarball to https://nominatim.org
-* [ ] prepare documentation
-  * check out new docs branch
-  * change git checkout instructions to tarball download instructions or adapt version on existing ones
-  * build documentation and copy to https://github.com/osm-search/nominatim-org-site
-  * add new version to history
-* [ ] check release tarball
-  * download tarball as per new documentation instructions
-  * compile and import Nominatim
-  * run `nominatim --version` to confirm correct version
-* [ ] tag new release and add a release on github.com

-# Install Nominatim in a virtual machine for development and testing
-
-This document describes how you can install Nominatim inside a Ubuntu 16
-virtual machine on your desktop/laptop (host machine). The goal is to give
-you a development environment to easily edit code and run the test suite
-without affecting the rest of your system. 
-
-The installation can run largely unsupervised. You should expect 1h from
-start to finish depending on how fast your computer and download speed
-is.
-
-## Prerequisites
-
-1. [Virtualbox](https://www.virtualbox.org/wiki/Downloads)
-
-2. [Vagrant](https://www.vagrantup.com/downloads.html)
-
-3. Nominatim 
-
-        git clone --recursive https://github.com/openstreetmap/Nominatim.git
-
-    If you forgot `--recursive`, it you can later load the submodules using
-    
-        git submodule init
-        git submodule update
-
-
-
-## Installation
-
-1. Start the virtual machine
-
-        vagrant up ubuntu
-
-2. Log into the virtual machine
-
-        vagrant ssh ubuntu
-
-3. Import a small country (Monaco)
-    
-    See the FAQ how to skip this step and point Nominatim to an existing database.
-
-      ```
-      # inside the virtual machine:
-      cd nominatim-project
-      wget --no-verbose --output-document=monaco.osm.pbf http://download.geofabrik.de/europe/monaco-latest.osm.pbf
-      nominatim import --osm-file monaco.osm.pbf 2>&1 | tee monaco.$$.log
-      ```
-
-    To repeat an import you'd need to delete the database first
-
-        dropdb --if-exists nominatim
-
-
-
-## Development
-
-Vagrant maps the virtual machine's port 8089 to your host machine. Thus you can
-see Nominatim in action on [localhost:8089](http://localhost:8089/nominatim/).
-
-You edit code on your host machine in any editor you like. There is no need to
-restart any software: just refresh your browser window.
-
-Note that the webserver uses files from the /build directory. If you change
-files in Nominatim/website or Nominatim/utils for example you first need to
-copy them into the /build directory by running the `cmake` step from the
-installation.
-
-PHP errors are written to `/var/log/apache2/error.log`.
-
-With `echo` and `var_dump()` you write into the output (HTML/XML/JSON) when
-you either add `&debug=1` to the URL (preferred) or set
-`@define('CONST_Debug', true);` in `settings/local.php`.
-
-In the Python BDD test you can use `logger.info()` for temporary debug
-statements.
-
-
-
-## Running unit tests
-
-    cd ~/Nominatim/tests/php
-    phpunit ./
-
-
-## Running PHP code style tests
-
-    cd ~/Nominatim
-    phpcs --colors .
-
-
-## Running functional tests
-
-Tests in `test/bdd/db` and `test/bdd/osm2pgsql` have to pass 100%. Other
-tests might require full planet-wide data. Sadly even if you have your own
-planet-wide data there will be enough differences to the openstreetmap.org
-installation to cause false positives in the other tests (see FAQ). 
-
-To run the full test suite
-
-    cd ~/Nominatim/test/bdd
-    behave -DBUILDDIR=/home/vagrant/build/ db osm2pgsql
-
-To run a single file
-
-    behave -DBUILDDIR=/home/vagrant/build/ api/lookup/simple.feature
-
-Or a single test by line number
-
-    behave -DBUILDDIR=/home/vagrant/build/ api/lookup/simple.feature:34
-    
-To run specific groups of tests you can add tags just before the `Scenario line`, e.g.
-
-    @bug-34
-    Scenario: address lookup for non-existing or invalid node, way, relation
-
-and then
-
-    behave -DBUILDDIR=/home/vagrant/build/ --tags @bug-34
-
-
-
-
-
-
-## FAQ
-
-##### Will it run on Windows?
-
-Yes, Vagrant and Virtualbox can be installed on MS Windows just fine. You need a 64bit
-version of Windows.
-
-
-##### Why Monaco, can I use another country?
-
-Of course! The Monaco import takes less than 30 minutes and works with 2GB RAM.
-
-##### Will the results be the same as those from nominatim.openstreetmap.org?
-
-No. Long running Nominatim installations will differ once new import features (or
-bug fixes) get added since those usually only get applied to new/changed data.
-
-Also this document skips the optional Wikipedia data import which affects ranking
-of search results. See [Nominatim installation](https://nominatim.org/release-docs/latest/admin/Installation) for details.
-
-##### Why Ubuntu? Can I test CentOS/Fedora/CoreOS/FreeBSD?
-
-There is a Vagrant script for CentOS available, but the Nominatim directory
-isn't symlinked/mounted to the host which makes development trickier. We used
-it mainly for debugging installation with SELinux.
-
-In general Nominatim will run in the other environments. The installation steps
-are slightly different, e.g. the name of the package manager, Apache2 package
-name, location of files. We chose Ubuntu because that is closest to the
-nominatim.openstreetmap.org production environment.
-
-You can configure/download other Vagrant boxes from [https://app.vagrantup.com/boxes/search](https://app.vagrantup.com/boxes/search).
-
-##### How can I connect to an existing database?
-
-Let's say you have a Postgres database named `nominatim_it` on server `your-server.com` and port `5432`. The Postgres username is `postgres`. You can edit `settings/local.php` and point Nominatim to it.
-
-    pgsql:host=your-server.com;port=5432;user=postgres;dbname=nominatim_it
-    
-No data import or restarting necessary.
-
-If the Postgres installation is behind a firewall, you can try
-
-    ssh -L 9999:localhost:5432 your-username@your-server.com
-
-inside the virtual machine. It will map the port to `localhost:9999` and then
-you edit `settings/local.php` with
-
-    @define('CONST_Database_DSN', 'pgsql:host=localhost;port=9999;user=postgres;dbname=nominatim_it');
-
-To access postgres directly remember to specify the hostname, e.g. `psql --host localhost --port 9999 nominatim_it`
-
-
-##### My computer is slow and the import takes too long. Can I start the virtual machine "in the cloud"?
-
-Yes. It's possible to start the virtual machine on [Amazon AWS (plugin)](https://github.com/mitchellh/vagrant-aws)
-or [DigitalOcean (plugin)](https://github.com/smdahlen/vagrant-digitalocean).

-# Advanced installations
-
-This page contains instructions for setting up multiple countries in 
-your Nominatim database. It is assumed that you have already successfully
-installed the Nominatim software itself, if not return to the 
-[installation page](Installation.md).
-
-## Importing multiple regions (without updates)
-
-To import multiple regions in your database you can simply give multiple
-OSM files to the import command:
-
-```
-nominatim import --osm-file file1.pbf --osm-file file2.pbf
-```
-
-If you already have imported a file and want to add another one, you can
-use the add-data function to import the additional data as follows:
-
-```
-nominatim add-data --file <FILE>
-nominatim refresh --postcodes
-nominatim index -j <NUMBER OF THREADS>
-```
-
-Please note that adding additional data is always significantly slower than
-the original import.
-
-## Importing multiple regions (with updates)
-
-If you want to import multiple regions _and_ be able to keep them up-to-date
-with updates, then you can use the scripts provided in the `utils` directory.
-
-These scripts will set up an `update` directory in your project directory,
-which has the following structure:
-
-```bash
-update
-    ├── europe
-    │   ├── andorra
-    │   │   └── sequence.state
-    │   └── monaco
-    │       └── sequence.state
-    └── tmp
-        └── europe
-                ├── andorra-latest.osm.pbf
-                └── monaco-latest.osm.pbf
-
-
-```
-
-The `sequence.state` files contain the sequence ID for each region. They will
-be used by pyosmium to get updates. The `tmp` folder is used for import dump and
-can be deleted once the import is complete.
-
-
-### Setting up multiple regions
-
-Create a project directory as described for the
-[simple import](Import.md#creating-the-project-directory). If necessary,
-you can also add an `.env` configuration with customized options. In particular,
-you need to make sure that `NOMINATIM_REPLICATION_UPDATE_INTERVAL` and
-`NOMINATIM_REPLICATION_RECHECK_INTERVAL` are set according to the update
-interval of the extract server you use.
-
-Copy the scripts `utils/import_multiple_regions.sh` and `utils/update_database.sh`
-into the project directory.
-
-Now customize both files as per your requirements
-
-1. List of countries. e.g.
-
-        COUNTRIES="europe/monaco europe/andorra"
-
-2. URL to the service providing the extracts and updates. eg:
-
-        BASEURL="https://download.geofabrik.de"
-        DOWNCOUNTRYPOSTFIX="-latest.osm.pbf"
-
-5. Followup in the update script can be set according to your installation.
-   E.g. for Photon,
-
-        FOLLOWUP="curl http://localhost:2322/nominatim-update"
-
-    will handle the indexing.
-
-
-To start the initial import, change into the project directory and run
-
-```
-    bash import_multiple_regions.sh
-```
-
-### Updating the database
-
-Change into the project directory and run the following command:
-
-    bash update_database.sh
-
-This will get diffs from the replication server, import diffs and index
-the database. The default replication server in the
-script([Geofabrik](https://download.geofabrik.de)) provides daily updates.
-
-## Using an external PostgreSQL database
-
-You can install Nominatim using a database that runs on a different server when
-you have physical access to the file system on the other server. Nominatim
-uses a custom normalization library that needs to be made accessible to the
-PostgreSQL server. This section explains how to set up the normalization
-library.
-
-!!! note
-    The external module is only needed when using the legacy tokenizer.
-    If you have chosen the ICU tokenizer, then you can ignore this section
-    and follow the standard import documentation.
-
-### Option 1: Compiling the library on the database server
-
-The most sure way to get a working library is to compile it on the database
-server. From the prerequisites you need at least cmake, gcc and the
-PostgreSQL server package.
-
-Clone or unpack the Nominatim source code, enter the source directory and
-create and enter a build directory.
-
-```sh
-cd Nominatim
-mkdir build
-cd build
-```
-
-Now configure cmake to only build the PostgreSQL module and build it:
-
-```
-cmake -DBUILD_IMPORTER=off -DBUILD_API=off -DBUILD_TESTS=off -DBUILD_DOCS=off -DBUILD_OSM2PGSQL=off ..
-make
-```
-
-When done, you find the normalization library in `build/module/nominatim.so`.
-Copy it to a place where it is readable and executable by the PostgreSQL server
-process.
-
-### Option 2: Compiling the library on the import machine
-
-You can also compile the normalization library on the machine from where you
-run the import.
-
-!!! important
-    You can only do this when the database server and the import machine have
-    the same architecture and run the same version of Linux. Otherwise there is
-    no guarantee that the compiled library is compatible with the PostgreSQL
-    server running on the database server.
-
-Make sure that the PostgreSQL server package is installed on the machine
-**with the same version as on the database server**. You do not need to install
-the PostgreSQL server itself.
-
-Download and compile Nominatim as per standard instructions. Once done, you find
-the normalization library in `build/module/nominatim.so`. Copy the file to
-the database server at a location where it is readable and executable by the
-PostgreSQL server process.
-
-### Running the import
-
-On the client side you now need to configure the import to point to the
-correct location of the library **on the database server**. Add the following
-line to your your `.env` file:
-
-```php
-NOMINATIM_DATABASE_MODULE_PATH="<directory on the database server where nominatim.so resides>"
-```
-
-Now change the `NOMINATIM_DATABASE_DSN` to point to your remote server and continue
-to follow the [standard instructions for importing](Import.md).
-
-
-## Moving the database to another machine
-
-For some configurations it may be useful to run the import on one machine, then
-move the database to another machine and run the Nominatim service from there.
-For example, you might want to use a large machine to be able to run the import
-quickly but only want a smaller machine for production because there is not so
-much load. Or you might want to do the import once and then replicate the
-database to many machines.
-
-The important thing to keep in mind when transferring the Nominatim installation
-is that you need to transfer the database _and the project directory_. Both
-parts are essential for your installation.
-
-The Nominatim database can be transferred using the `pg_dump`/`pg_restore` tool.
-Make sure to use the same version of PostgreSQL and PostGIS on source and
-target machine.
-
-!!! note
-    Before creating a dump of your Nominatim database, consider running
-    `nominatim freeze` first. Your database looses the ability to receive further
-    data updates but the resulting database is only about a third of the size
-    of a full database.
-
-Next install Nominatim on the target machine by following the standard installation
-instructions. Again, make sure to use the same version as the source machine.
-
-Create a project directory on your destination machine and set up the `.env`
-file to match the configuration on the source machine. Finally run
-
-    nominatim refresh --website
-
-to make sure that the local installation of Nominatim will be used.
-
-If you are using the legacy tokenizer you might also have to switch to the
-PostgreSQL module that was compiled on your target machine. If you get errors
-that PostgreSQL cannot find or access `nominatim.so` then rerun
-
-   nominatim refresh --functions
-
-on the target machine to update the the location of the module.

-# Deploying Nominatim
-
-The Nominatim API is implemented as a PHP application. The `website/` directory
-in the project directory contains the configured website. You can serve this
-in a production environment with any web server that is capable to run
-PHP scripts.
-
-This section gives a quick overview on how to configure Apache and Nginx to
-serve Nominatim. It is not meant as a full system administration guide on how
-to run a web service. Please refer to the documentation of
-[Apache](http://httpd.apache.org/docs/current/) and
-[Nginx](https://nginx.org/en/docs/)
-for background information on configuring the services.
-
-!!! Note
-    Throughout this page, we assume that your Nominatim project directory is
-    located in `/srv/nominatim-project` and that you have installed Nominatim
-    using the default installation prefix `/usr/local`. If you have put it
-    somewhere else, you need to adjust the commands and configuration
-    accordingly.
-
-    We further assume that your web server runs as user `www-data`. Older
-    versions of CentOS may still use the user name `apache`. You also need
-    to adapt the instructions in this case.
-
-## Making the website directory accessible
-
-You need to make sure that the `website` directory is accessible for the
-web server user. You can check that the permissions are correct by accessing
-on of the php files as the web server user:
-
-``` sh
-sudo -u www-data head -n 1 /srv/nominatim-project/website/search.php
-```
-
-If this shows a permission error, then you need to adapt the permissions of
-each directory in the path so that it is executable for `www-data`.
-
-If you have SELinux enabled, further adjustments may be necessary to give the
-web server access. At a minimum the following SELinux labelling should be done
-for Nominatim:
-
-``` sh
-sudo semanage fcontext -a -t httpd_sys_content_t "/usr/local/nominatim/lib/lib-php(/.*)?"
-sudo semanage fcontext -a -t httpd_sys_content_t "/srv/nominatim-project/website(/.*)?"
-sudo semanage fcontext -a -t lib_t "/srv/nominatim-project/module/nominatim.so"
-sudo restorecon -R -v /usr/local/lib/nominatim
-sudo restorecon -R -v /srv/nominatim-project
-```
-
-## Nominatim with Apache
-
-### Installing the required packages
-
-With Apache you can use the PHP module to run Nominatim.
-
-Under Ubuntu/Debian install them with:
-
-``` sh
-sudo apt install apache2 libapache2-mod-php
-```
-
-### Configuring Apache
-
-Make sure your Apache configuration contains the required permissions for the
-directory and create an alias:
-
-``` apache
-<Directory "/srv/nominatim-project/website">
-  Options FollowSymLinks MultiViews
-  AddType text/html   .php
-  DirectoryIndex search.php
-  Require all granted
-</Directory>
-Alias /nominatim /srv/nominatim-project/website
-```
-
-After making changes in the apache config you need to restart apache.
-The website should now be available on `http://localhost/nominatim`.
-
-## Nominatim with Nginx
-
-### Installing the required packages
-
-Nginx has no built-in PHP interpreter. You need to use php-fpm as a daemon for
-serving PHP cgi.
-
-On Ubuntu/Debian install nginx and php-fpm with:
-
-``` sh
-sudo apt install nginx php-fpm
-```
-
-### Configure php-fpm and Nginx
-
-By default php-fpm listens on a network socket. If you want it to listen to a
-Unix socket instead, change the pool configuration
-(`/etc/php/<php version>/fpm/pool.d/www.conf`) as follows:
-
-``` ini
-; Replace the tcp listener and add the unix socket
-listen = /var/run/php-fpm-nominatim.sock
-
-; Ensure that the daemon runs as the correct user
-listen.owner = www-data
-listen.group = www-data
-listen.mode = 0666
-```
-
-Tell nginx that php files are special and to fastcgi_pass to the php-fpm
-unix socket by adding the location definition to the default configuration.
-
-``` nginx
-root /srv/nominatim-project/website;
-index search.php;
-location / {
-    try_files $uri $uri/ @php;
-}
-
-location @php {
-    fastcgi_param SCRIPT_FILENAME "$document_root$uri.php";
-    fastcgi_param PATH_TRANSLATED "$document_root$uri.php";
-    fastcgi_param QUERY_STRING    $args;
-    fastcgi_pass unix:/var/run/php-fpm-nominatim.sock;
-    fastcgi_index index.php;
-    include fastcgi_params;
-}
-
-location ~ [^/]\.php(/|$) {
-    fastcgi_split_path_info ^(.+?\.php)(/.*)$;
-    if (!-f $document_root$fastcgi_script_name) {
-        return 404;
-    }
-    fastcgi_pass unix:/var/run/php-fpm-nominatim.sock;
-    fastcgi_index search.php;
-    include fastcgi.conf;
-}
-```
-
-Restart the nginx and php-fpm services and the website should now be available
-at `http://localhost/`.

-# Troubleshooting Nominatim Installations
-
-## Installation Issues
-
-### Can a stopped/killed import process be resumed?
-
-"I accidentally killed the import process after it has been running for many hours. Can it be resumed?"
-
-It is possible if the import already got to the indexing stage.
-Check the last line of output that was logged before the process
-was killed. If it looks like this:
-
-
-    Done 844 in 13 @ 64.923080 per second - Rank 26 ETA (seconds): 7.886255
-
-then you can resume with the following command:
-
-```sh
-nominatim import --continue indexing
-```
-
-If the reported rank is 26 or higher, you can also safely add `--index-noanalyse`.
-
-
-### PostgreSQL crashed "invalid page in block"
-
-Usually serious problem, can be a hardware issue, not all data written to disc
-for example. Check PostgreSQL log file and search PostgreSQL issues/mailing
-list for hints.
-
-If it happened during index creation you can try rerunning the step with
-
-```sh
-nominatim import --continue indexing
-```
-
-Otherwise it's best to start the full setup from the beginning.
-
-
-### PHP "open_basedir restriction in effect" warnings
-
-    PHP Warning:  file_get_contents(): open_basedir restriction in effect.
-
-You need to adjust the
-[open_basedir](https://www.php.net/manual/en/ini.core.php#ini.open-basedir)
-setting in your PHP configuration (`php.ini` file). By default this setting may
-look like this:
-
-    open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/
-
-Either add reported directories to the list or disable this setting temporarily
-by adding ";" at the beginning of the line. Don't forget to enable this setting
-again once you are done with the PHP command line operations.
-
-
-### PHP timezeone warnings
-
-The Apache log may contain lots of PHP warnings like this:
-    `PHP Warning:  date_default_timezone_set() function.`
-
-You should set the default time zone as instructed in the warning in
-your `php.ini` file. Find the entry about timezone and set it to
-something like this:
-
-    ; Defines the default timezone used by the date functions
-    ; https://php.net/date.timezone
-    date.timezone = 'America/Denver'
-
-Or
-
-```
-echo "date.timezone = 'America/Denver'" > /etc/php.d/timezone.ini
-```
-
-### nominatim.so version mismatch
-
-When running the import you may get a version mismatch:
-`COPY_END for place failed: ERROR: incompatible library "/srv/Nominatim/nominatim/build/module/nominatim.so": version mismatch`
-
-pg_config seems to use bad includes sometimes when multiple versions
-of PostgreSQL are available in the system. Make sure you remove the
-server development libraries (`postgresql-server-dev-13` on Ubuntu)
-and recompile (`cmake .. && make`).
-
-
-### I see the error "ERROR: permission denied for language c"
-
-`nominatim.so`, written in C, is required to be installed on the database
-server. Some managed database (cloud) services like Amazon RDS do not allow
-this. There is currently no work-around other than installing a database
-on a non-managed machine.
-
-
-### I see the error: "function transliteration(text) does not exist"
-
-Reinstall the nominatim functions with `nominatim refresh --functions`
-and check for any errors, e.g. a missing `nominatim.so` file.
-
-### I see the error: "ERROR: mmap (remap) failed"
-
-This may be a simple out-of-memory error. Try reducing the memory used
-for `--osm2pgsql-cache`. Also make sure that overcommitting memory is
-allowed: `cat /proc/sys/vm/overcommit_memory` should print 0 or 1.
-
-If you are using a flatnode file, then it may also be that the underlying
-filesystem does not fully support 'mmap'. A notable candidate is virtualbox's
-vboxfs.
-
-### nominatim UPDATE failed: ERROR: buffer 179261 is not owned by resource owner Portal
-
-Several users [reported this](https://github.com/openstreetmap/Nominatim/issues/1168)
-during the initial import of the database. It's
-something PostgreSQL internal Nominatim doesn't control. And PostgreSQL forums
-suggest it's threading related but definitely some kind of crash of a process.
-Users reported either rebooting the server, different hardware or just trying
-the import again worked.
-
-### The website shows: "Could not get word tokens"
-
-The server cannot access your database. Add `&debug=1` to your URL
-to get the full error message.
-
-
-### Website reports "DB Error: insufficient permissions"
-
-The user the webserver, e.g. Apache, runs under needs to have access to the
-Nominatim database. You can find the user like
-[this](https://serverfault.com/questions/125865/finding-out-what-user-apache-is-running-as),
-for default Ubuntu operating system for example it's `www-data`.
-
-1. Repeat the `createuser` step of the installation instructions.
-
-2. Give the user permission to existing tables
-
-```
-   GRANT usage ON SCHEMA public TO "www-data";
-   GRANT SELECT ON ALL TABLES IN SCHEMA public TO "www-data";
-```
-
-### Website reports "Could not load library "nominatim.so"
-
-Example error message
-
-```
-   SELECT make_standard_name('3039 E MEADOWLARK LN') [nativecode=ERROR: could not
-   load library "/srv/nominatim/Nominatim-3.1.0/build/module/nominatim.so":
-   /srv/nominatim/Nominatim-3.1.0/build/module/nominatim.so: cannot open shared
-   object file: Permission denied
-   CONTEXT: PL/pgSQL function make_standard_name(text) line 5 at assignment]
-```
-
-The PostgreSQL database, i.e. user `postgres`, needs to have access to that file.
-
-The permission need to be read & executable by everybody, but not writeable
-by everybody, e.g.
-
-```
-   -rwxr-xr-x 1 nominatim nominatim 297984 build/module/nominatim.so
-```
-
-Try `chmod a+r nominatim.so; chmod a+x nominatim.so`.
-
-When you recently updated your operating system, updated PostgreSQL to
-a new version or moved files (e.g. the build directory) you should
-recreate `nominatim.so`. Try
-
-```
-   cd build
-   rm -r module/
-   cmake $main_Nominatim_path && make
-```
-
-### Setup.php fails with "DB Error: extension not found"
-
-Make sure you have the PostgreSQL extensions "hstore" and "postgis" installed.
-See the installation instructions for a full list of required packages.
-
-
-### I forgot to delete the flatnodes file before starting an import.
-
-That's fine. For each import the flatnodes file get overwritten.
-See [https://help.openstreetmap.org/questions/52419/nominatim-flatnode-storage](https://help.openstreetmap.org/questions/52419/nominatim-flatnode-storage)
-for more information.

-# Importing the Database
-
-The following instructions explain how to create a Nominatim database
-from an OSM planet file. It is assumed that you have already successfully
-installed the Nominatim software itself and the `nominatim` tool can be found
-in your `PATH`. If this is not the case, return to the
-[installation page](Installation.md).
-
-## Creating the project directory
-
-Before you start the import, you should create a project directory for your
-new database installation. This directory receives all data that is related
-to a single Nominatim setup: configuration, extra data, etc. Create a project
-directory apart from the Nominatim software and change into the directory:
-
-```
-mkdir ~/nominatim-planet
-cd ~/nominatim-planet
-```
-
-In the following, we refer to the project directory as `$PROJECT_DIR`. To be
-able to copy&paste instructions, you can export the appropriate variable:
-
-```
-export PROJECT_DIR=~/nominatim-planet
-```
-
-The Nominatim tool assumes per default that the current working directory is
-the project directory but you may explicitly state a different directory using
-the `--project-dir` parameter. The following instructions assume that you run
-all commands from the project directory.
-
-!!! tip "Migration Tip"
-
-    Nominatim used to be run directly from the build directory until version 3.6.
-    Essentially, the build directory functioned as the project directory
-    for the database installation. This setup still works and can be useful for
-    development purposes. It is not recommended anymore for production setups.
-    Create a project directory that is separate from the Nominatim software.
-
-### Configuration setup in `.env`
-
-The Nominatim server can be customized via an `.env` configuration file in the 
-project directory. This is a file in [dotenv](https://github.com/theskumar/python-dotenv)
-format which looks the same as variable settings in a standard shell environment.
-You can also set the same configuration via environment variables. All
-settings have a `NOMINATIM_` prefix to avoid conflicts with other environment
-variables.
-
-There are lots of configuration settings you can tweak. A full reference
-can be found in the chapter [Configuration Settings](../customize/Settings.md).
-Most should have a sensible default.
-
-#### Flatnode files
-
-If you plan to import a large dataset (e.g. Europe, North America, planet),
-you should also enable flatnode storage of node locations. With this
-setting enabled, node coordinates are stored in a simple file instead
-of the database. This will save you import time and disk storage.
-Add to your `.env`:
-
-    NOMINATIM_FLATNODE_FILE="/path/to/flatnode.file"
-
-Replace the second part with a suitable path on your system and make sure
-the directory exists. There should be at least 75GB of free space.
-
-## Downloading additional data
-
-### Wikipedia/Wikidata rankings
-
-Wikipedia can be used as an optional auxiliary data source to help indicate
-the importance of OSM features. Nominatim will work without this information
-but it will improve the quality of the results if this is installed.
-This data is available as a binary download. Put it into your project directory:
-
-    cd $PROJECT_DIR
-    wget https://nominatim.org/data/wikimedia-importance.sql.gz
-
-The file is about 400MB and adds around 4GB to the Nominatim database.
-
-!!! tip
-    If you forgot to download the wikipedia rankings, then you can
-    also add importances after the import. Download the SQL files, then
-    run `nominatim refresh --wiki-data --importance`. Updating
-    importances for a planet will take a couple of hours.
-
-### External postcodes
-
-Nominatim can use postcodes from an external source to improve searching with
-postcodes. We provide precomputed postcodes sets for the US (using TIGER data)
-and the UK (using the [CodePoint OpenData set](https://osdatahub.os.uk/downloads/open/CodePointOpen).
-This data can be optionally downloaded into the project directory:
-
-    cd $PROJECT_DIR
-    wget https://nominatim.org/data/gb_postcodes.csv.gz
-    wget https://nominatim.org/data/us_postcodes.csv.gz
-
-You can also add your own custom postcode sources, see
-[Customization of postcodes](../customize/Postcodes.md).
-
-## Choosing the data to import
-
-In its default setup Nominatim is configured to import the full OSM data
-set for the entire planet. Such a setup requires a powerful machine with
-at least 64GB of RAM and around 900GB of SSD hard disks. Depending on your
-use case there are various ways to reduce the amount of data imported. This
-section discusses these methods. They can also be combined.
-
-### Using an extract
-
-If you only need geocoding for a smaller region, then precomputed OSM extracts
-are a good way to reduce the database size and import time.
-[Geofabrik](https://download.geofabrik.de) offers extracts for most countries.
-They even have daily updates which can be used with the update process described
-[in the next section](Update.md). There are also
-[other providers for extracts](https://wiki.openstreetmap.org/wiki/Planet.osm#Downloading).
-
-Please be aware that some extracts are not cut exactly along the country
-boundaries. As a result some parts of the boundary may be missing which means
-that Nominatim cannot compute the areas for some administrative areas.
-
-### Dropping Data Required for Dynamic Updates
-
-About half of the data in Nominatim's database is not really used for serving
-the API. It is only there to allow the data to be updated from the latest
-changes from OSM. For many uses these dynamic updates are not really required.
-If you don't plan to apply updates, you can run the import with the
-`--no-updates` parameter. This will drop the dynamic part of the database as
-soon as it is not required anymore.
-
-You can also drop the dynamic part later using the following command:
-
-```
-nominatim freeze
-```
-
-Note that you still need to provide for sufficient disk space for the initial
-import. So this option is particularly interesting if you plan to transfer the
-database or reuse the space later.
-
-!!! warning
-    The data structure for updates are also required when adding additional data
-    after the import, for example [TIGER housenumber data](../customize/Tiger.md).
-    If you plan to use those, you must not use the `--no-updates` parameter.
-    Do a normal import, add the external data and once you are done with
-    everything run `nominatim freeze`.
-
-
-### Reverse-only Imports
-
-If you only want to use the Nominatim database for reverse lookups or
-if you plan to use the installation only for exports to a
-[photon](https://photon.komoot.io/) database, then you can set up a database
-without search indexes. Add `--reverse-only` to your setup command above.
-
-This saves about 5% of disk space.
-
-### Filtering Imported Data
-
-Nominatim normally sets up a full search database containing administrative
-boundaries, places, streets, addresses and POI data. There are also other
-import styles available which only read selected data:
-
-* **admin**
-  Only import administrative boundaries and places.
-* **street**
-  Like the admin style but also adds streets.
-* **address**
-  Import all data necessary to compute addresses down to house number level.
-* **full**
-  Default style that also includes points of interest.
-* **extratags**
-  Like the full style but also adds most of the OSM tags into the extratags
-  column.
-
-The style can be changed with the configuration `NOMINATIM_IMPORT_STYLE`.
-
-To give you an idea of the impact of using the different styles, the table
-below gives rough estimates of the final database size after import of a
-2020 planet and after using the `--drop` option. It also shows the time
-needed for the import on a machine with 64GB RAM, 4 CPUS and NVME disks.
-Note that the given sizes are just an estimate meant for comparison of
-style requirements. Your planet import is likely to be larger as the
-OSM data grows with time.
-
-style     | Import time  |  DB size   |  after drop
-----------|--------------|------------|------------
-admin     |    4h        |  215 GB    |   20 GB
-street    |   22h        |  440 GB    |  185 GB
-address   |   36h        |  545 GB    |  260 GB
-full      |   54h        |  640 GB    |  330 GB
-extratags |   54h        |  650 GB    |  340 GB
-
-You can also customize the styles further.
-A [description of the style format](../customize/Import-Styles.md)
-can be found in the customization guide.
-
-## Initial import of the data
-
-!!! danger "Important"
-    First try the import with a small extract, for example from
-    [Geofabrik](https://download.geofabrik.de).
-
-Download the data to import. Then issue the following command
-from the **project directory** to start the import:
-
-```sh
-nominatim import --osm-file <data file> 2>&1 | tee setup.log
-```
-
-The **project directory** is the one that you have set up at the beginning.
-See [creating the project directory](#creating-the-project-directory).
-
-### Notes on full planet imports
-
-Even on a perfectly configured machine
-the import of a full planet takes around 2 days. Once you see messages
-with `Rank .. ETA` appear, the indexing process has started. This part takes
-the most time. There are 30 ranks to process. Rank 26 and 30 are the most complex.
-They take each about a third of the total import time. If you have not reached
-rank 26 after two days of import, it is worth revisiting your system
-configuration as it may not be optimal for the import.
-
-### Notes on memory usage
-
-In the first step of the import Nominatim uses [osm2pgsql](https://osm2pgsql.org)
-to load the OSM data into the PostgreSQL database. This step is very demanding
-in terms of RAM usage. osm2pgsql and PostgreSQL are running in parallel at 
-this point. PostgreSQL blocks at least the part of RAM that has been configured
-with the `shared_buffers` parameter during
-[PostgreSQL tuning](Installation.md#postgresql-tuning)
-and needs some memory on top of that. osm2pgsql needs at least 2GB of RAM for
-its internal data structures, potentially more when it has to process very large
-relations. In addition it needs to maintain a cache for node locations. The size
-of this cache can be configured with the parameter `--osm2pgsql-cache`.
-
-When importing with a flatnode file, it is best to disable the node cache
-completely and leave the memory for the flatnode file. Nominatim will do this
-by default, so you do not need to configure anything in this case.
-
-For imports without a flatnode file, set `--osm2pgsql-cache` approximately to
-the size of the OSM pbf file you are importing. The size needs to be given in
-MB. Make sure you leave enough RAM for PostgreSQL and osm2pgsql as mentioned
-above. If the system starts swapping or you are getting out-of-memory errors,
-reduce the cache size or even consider using a flatnode file.
-
-
-### Testing the installation
-
-Run this script to verify that all required tables and indices got created
-successfully.
-
-```sh
-nominatim admin --check-database
-```
-
-Now you can try out your installation by running:
-
-```sh
-nominatim serve
-```
-
-This runs a small test server normally used for development. You can use it
-to verify that your installation is working. Go to
-`http://localhost:8088/status.php` and you should see the message `OK`.
-You can also run a search query, e.g. `http://localhost:8088/search.php?q=Berlin`.
-
-Note that search query is not supported for reverse-only imports. You can run a
-reverse query, e.g. `http://localhost:8088/reverse.php?lat=27.1750090510034&lon=78.04209025`.
-
-To run Nominatim via webservers like Apache or nginx, please read the
-[Deployment chapter](Deployment.md).
-
-## Adding search through category phrases
-
-If you want to be able to search for places by their type through
-[special phrases](https://wiki.openstreetmap.org/wiki/Nominatim/Special_Phrases)
-you also need to import these key phrases like this:
-
-```sh
-nominatim special-phrases --import-from-wiki
-```
-
-Note that this command downloads the phrases from the wiki link above. You
-need internet access for the step.
-
-You can also import special phrases from a csv file, for more 
-information please see the [Customization part](../customize/Special-Phrases.md).

-
-## Prerequisites
-
-### Software
-
-!!! Warning
-    For larger installations you **must have** PostgreSQL 11+ and PostGIS 3+
-    otherwise import and queries will be slow to the point of being unusable.
-    Query performance has marked improvements with PostgreSQL 13+ and PostGIS 3.2+.
-
-For compiling:
-
-  * [cmake](https://cmake.org/)
-  * [expat](https://libexpat.github.io/)
-  * [proj](https://proj.org/)
-  * [bzip2](http://www.bzip.org/)
-  * [zlib](https://www.zlib.net/)
-  * [ICU](http://site.icu-project.org/)
-  * [Boost libraries](https://www.boost.org/), including system and filesystem
-  * PostgreSQL client libraries
-  * a recent C++ compiler (gcc 5+ or Clang 3.8+)
-
-For running Nominatim:
-
-  * [PostgreSQL](https://www.postgresql.org) (9.6+ will work, 11+ strongly recommended)
-  * [PostGIS](https://postgis.net) (2.2+ will work, 3.0+ strongly recommended)
-  * [Python 3](https://www.python.org/) (3.6+)
-  * [Psycopg2](https://www.psycopg.org) (2.7+)
-  * [Python Dotenv](https://github.com/theskumar/python-dotenv)
-  * [psutil](https://github.com/giampaolo/psutil)
-  * [Jinja2](https://palletsprojects.com/p/jinja/)
-  * [PyICU](https://pypi.org/project/PyICU/)
-  * [PyYaml](https://pyyaml.org/) (5.1+)
-  * [datrie](https://github.com/pytries/datrie)
-  * [PHP](https://php.net) (7.0 or later)
-  * PHP-pgsql
-  * PHP-intl (bundled with PHP)
-  * PHP-cgi (for running queries from the command line)
-
-For running continuous updates:
-
-  * [pyosmium](https://osmcode.org/pyosmium/)
-
-For dependencies for running tests and building documentation, see
-the [Development section](../develop/Development-Environment.md).
-
-### Hardware
-
-A minimum of 2GB of RAM is required or installation will fail. For a full
-planet import 128GB of RAM or more are strongly recommended. Do not report
-out of memory problems if you have less than 64GB RAM.
-
-For a full planet install you will need at least 1TB of hard disk space.
-Take into account that the OSM database is growing fast.
-Fast disks are essential. Using NVME disks is recommended.
-
-Even on a well configured machine the import of a full planet takes
-around 2 days. On traditional spinning disks, 7-8 days are more realistic.
-
-## Tuning the PostgreSQL database
-
-You might want to tune your PostgreSQL installation so that the later steps
-make best use of your hardware. You should tune the following parameters in
-your `postgresql.conf` file.
-
-    shared_buffers = 2GB
-    maintenance_work_mem = (10GB)
-    autovacuum_work_mem = 2GB
-    work_mem = (50MB)
-    effective_cache_size = (24GB)
-    synchronous_commit = off
-    max_wal_size = 1GB
-    checkpoint_timeout = 10min
-    checkpoint_completion_target = 0.9
-
-The numbers in brackets behind some parameters seem to work fine for
-64GB RAM machine. Adjust to your setup. A higher number for `max_wal_size`
-means that PostgreSQL needs to run checkpoints less often but it does require
-the additional space on your disk.
-
-Autovacuum must not be switched off because it ensures that the
-tables are frequently analysed. If your machine has very little memory,
-you might consider setting:
-
-    autovacuum_max_workers = 1
-
-and even reduce `autovacuum_work_mem` further. This will reduce the amount
-of memory that autovacuum takes away from the import process.
-
-For the initial import, you should also set:
-
-    fsync = off
-    full_page_writes = off
-
-Don't forget to re-enable them after the initial import or you risk database
-corruption.
-
-
-## Downloading and building Nominatim
-
-### Downloading the latest release
-
-You can download the [latest release from nominatim.org](https://nominatim.org/downloads/).
-The release contains all necessary files. Just unpack it.
-
-### Downloading the latest development version
-
-If you want to install latest development version from github, make sure to
-also check out the osm2pgsql subproject:
-
-```
-git clone --recursive https://github.com/openstreetmap/Nominatim.git
-```
-
-The development version does not include the country grid. Download it separately:
-
-```
-wget -O Nominatim/data/country_osm_grid.sql.gz https://nominatim.org/data/country_grid.sql.gz
-```
-
-### Building Nominatim
-
-The code must be built in a separate directory. Create the directory and
-change into it.
-
-```
-mkdir build
-cd build
-```
-
-Nominatim uses cmake and make for building. Assuming that you have created the
-build at the same level as the Nominatim source directory run:
-
-```
-cmake ../Nominatim
-make
-sudo make install
-```
-
-!!! warning
-    The default installation no longer compiles the PostgreSQL module that
-    is needed for the legacy tokenizer from older Nominatim versions. If you
-    are upgrading an older database or want to run the
-    [legacy tokenizer](../customize/Tokenizers.md#legacy-tokenizer) for
-    some other reason, you need to enable the PostgreSQL module via
-    cmake: `cmake -DBUILD_MODULE=on ../Nominatim`. To compile the module
-    you need to have the server development headers for PostgreSQL installed.
-    On Ubuntu/Debian run: `sudo apt install postgresql-server-dev-<postgresql version>`
-
-
-Nominatim installs itself into `/usr/local` per default. To choose a different
-installation directory add `-DCMAKE_INSTALL_PREFIX=<install root>` to the
-cmake command. Make sure that the `bin` directory is available in your path
-in that case, e.g.
-
-```
-export PATH=<install root>/bin:$PATH
-```
-
-Now continue with [importing the database](Import.md).

docs/admin/Maintenance.md

@@ -1,75 +0,0 @@
-This chapter describes the various operations the Nominatim database administrator
-may use to clean and maintain the database. None of these operations is mandatory
-but they may help improve the performance and accuracy of results.
-
-
-## Updating postcodes
-
-Command: `nominatim refresh --postcodes`
-
-Postcode centroids (aka 'calculated postcodes') are generated by looking at all
-postcodes of a country, grouping them and calculating the geometric centroid.
-There is currently no logic to deal with extreme outliers (typos or other
-mistakes in OSM data). There is also no check if a postcodes adheres to a
-country's format, e.g. if Swiss postcodes are 4 digits.
-
-When running regular updates, postcodes results can be improved by running
-this command on a regular basis. Note that only the postcode table and the
-postcode search terms are updated. The postcode that is assigned to each place
-is only updated when the place is updated.
-
-The command takes around 70min to run on the planet and needs ca. 40GB of
-temporary disk space.
-
-
-## Updating word counts
-
-Command: `nominatim refresh --word-counts`
-
-Nominatim keeps frequency statistics about all search terms it indexes. These
-statistics are currently used to optimise queries to the database. Thus better
-statistics mean better performance. Word counts are created once after import
-and are usually sufficient even when running regular updates. You might want
-to rerun the statistics computation when adding larger amounts of new data,
-for example, when adding an additional country via `nominatim add-data`.
-
-
-## Forcing recomputation of places and areas
-
-Command: `nominatim refresh --data-object [NWR]<id> --data-area [NWR]<id>`
-
-When running replication updates, Nominatim tries to recompute the search
-and address information for all places that are affected by a change. But it
-needs to restrict the total number of changes to make sure it can keep up
-with the minutely updates. Therefore it will refrain from propagating changes
-that affect a lot of objects.
-
-The administrator may force an update of places in the database.
-`nominatim refresh --data-object` invalidates a single OSM object.
-`nominatim refresh --data-area` invalidates an OSM object and all dependent
-objects. That are usually the places that inside its area or around the
-center of the object. Both commands expect the OSM object as an argument
-of the form OSM type + OSM id. The type must be `N` (node), `W` (way) or
-`R` (relation).
-
-After invalidating the object, indexing must be run again. If continuous
-update are running in the background, the objects will be recomputed together
-with the next round of updates. Otherwise you need to run `nominatim index`
-to finish the recomputation.
-
-
-## Removing large deleted objects
-
-Nominatim refuses to delete very large areas because often these deletions are
-accidental and are reverted within hours. Instead the deletions are logged in
-the `import_polygon_delete` table and left to the administrator to clean up.
-
-There is currently no command to do that. You can use the following SQL
-query to force a deletion on all objects that have been deleted more than
-a certain timespan ago (here: 1 month):
-
-```sql
-SELECT place_force_delete(p.place_id) FROM import_polygon_delete d, placex p
-WHERE p.osm_type = d.osm_type and p.osm_id = d.osm_id
-      and age(p.indexed_date) > '1 month'::interval
-```

-# Database Migrations
-
-Since version 3.7.0 Nominatim offers automatic migrations. Please follow
-the following steps:
-
-* stop any updates that are potentially running
-* update Nominatim to the newer version
-* go to your project directory and run `nominatim admin --migrate`
-* (optionally) restart updates
-
-Below you find additional migrations and hints about other structural and
-breaking changes. **Please read them before running the migration.**
-
-!!! note
-    If you are migrating from a version <3.6, then you still have to follow
-    the manual migration steps up to 3.6.
-
-## 4.2.2 -> 4.2.3
-
-### Update interpolation functions
-
-When updating to this release, you need to run `nominatim refresh --functions`
-after updating and before restarting updates. Otherwise you may see an error
-`Splitting of Point geometries is unsupported` or similar.
-
-## 4.0.0 -> 4.1.0
-
-### ICU tokenizer is the new default
-
-Nominatim now installs the [ICU tokenizer](../customize/Tokenizers.md#icu-tokenizer)
-by default. This only has an effect on newly installed databases. When
-updating older databases, it keeps its installed tokenizer. If you still
-run with the legacy tokenizer, make sure to compile Nominatim with the
-PostgreSQL module, see [Installation](Installation.md#building-nominatim).
-
-### geocodejson output changed
-
-The `type` field of the geocodejson output has changed. It now contains
-the address class of the object instead of the value of the OSM tag. If
-your client has used the `type` field, switch them to read `osm_value`
-instead.
-
-## 3.7.0 -> 4.0.0
-
-### NOMINATIM_PHRASE_CONFIG removed
-
-Custom blacklist configurations for special phrases now need to be handed
-with the `--config` parameter to `nominatim special-phrases`. Alternatively
-you can put your custom configuration in the project directory in a file
-named `phrase-settings.json`.
-
-Version 3.8 also removes the automatic converter for the php format of
-the configuration in older versions. If you are updating from Nominatim < 3.7
-and still work with a custom `phrase-settings.php`, you need to manually
-convert it into a json format.
-
-### PHP utils removed
-
-The old PHP utils have now been removed completely. You need to switch to
-the appropriate functions of the nominatim  command line tool. See
-[Introducing `nominatim` command line tool](#introducing-nominatim-command-line-tool)
-below.
-
-## 3.6.0 -> 3.7.0
-
-### New format and name of configuration file
-
-The configuration for an import is now saved in a `.env` file in the project
-directory. This file follows the dotenv format. For more information, see
-the [installation chapter](Import.md#configuration-setup-in-env).
-
-To migrate to the new system, create a new project directory, add the `.env`
-file and port your custom configuration from `settings/local.php`. Most
-settings are named similar and only have received a `NOMINATIM_` prefix.
-Use the default settings in `settings/env.defaults` as a reference.
-
-### New location for data files
-
-External data files for Wikipedia importance, postcodes etc. are no longer
-expected to reside in the source tree by default. Instead they will be searched
-in the project directory. If you have an automated setup script you must
-either adapt the download location or explicitly set the location of the
-files to the old place in your `.env`.
-
-### Introducing `nominatim` command line tool
-
-The various php utilities have been replaced with a single `nominatim`
-command line tool. Make sure to adapt any scripts. There is no direct 1:1
-matching between the old utilities and the commands of nominatim CLI. The
-following list gives you a list of nominatim sub-commands that contain
-functionality of each script:
-
-* ./utils/setup.php: `import`, `freeze`, `refresh`
-* ./utils/update.php: `replication`, `add-data`, `index`, `refresh`
-* ./utils/specialphrases.php: `special-phrases`
-* ./utils/check_import_finished.php: `admin`
-* ./utils/warm.php: `admin`
-* ./utils/export.php: `export`
-
-Try `nominatim <command> --help` for more information about each subcommand.
-
-`./utils/query.php` no longer exists in its old form. `nominatim search`
-provides a replacement but returns different output.
-
-### Switch to normalized house numbers
-
-The housenumber column in the placex table uses now normalized version.
-The automatic migration step will convert the column but this may take a
-very long time. It is advisable to take the machine offline while doing that.
-
-## 3.5.0 -> 3.6.0
-
-### Change of layout of search_name_* tables
-
-The table need a different index for nearest place lookup. Recreate the
-indexes using the following shell script:
-
-```bash
-for table in `psql -d nominatim -c "SELECT tablename FROM pg_tables WHERE tablename LIKE 'search_name_%'" -tA | grep -v search_name_blank`;
-do
-    psql -d nominatim -c "DROP INDEX idx_${table}_centroid_place; CREATE INDEX idx_${table}_centroid_place ON ${table} USING gist (centroid) WHERE ((address_rank >= 2) AND (address_rank <= 25)); DROP INDEX idx_${table}_centroid_street; CREATE INDEX idx_${table}_centroid_street ON ${table} USING gist (centroid) WHERE ((address_rank >= 26) AND (address_rank <= 27))";
-done
-```
-
-### Removal of html output
-
-The debugging UI is no longer directly provided with Nominatim. Instead we
-now provide a simple Javascript application. Please refer to
-[Setting up the Nominatim UI](Setup-Nominatim-UI.md) for details on how to
-set up the UI.
-
-The icons served together with the API responses have been moved to the
-nominatim-ui project as well. If you want to keep the `icon` field in the
-response, you need to set `CONST_MapIcon_URL` to the URL of the `/mapicon`
-directory of nominatim-ui.
-
-### Change order during indexing
-
-When reindexing places during updates, there is now a different order used
-which needs a different database index. Create it with the following SQL command:
-
-```sql
-CREATE INDEX idx_placex_pendingsector_rank_address
-  ON placex
-  USING BTREE (rank_address, geometry_sector)
-  WHERE indexed_status > 0;
-```
-
-You can then drop the old index with:
-
-```sql
-DROP INDEX idx_placex_pendingsector;
-```
-
-### Unused index
-
-This index has been unused ever since the query using it was changed two years ago. Saves about 12GB on a planet installation.
-
-```sql
-DROP INDEX idx_placex_geometry_reverse_lookupPoint;
-```
-
-### Switching to dotenv
-
-As part of the work changing the configuration format, the configuration for
-the website is now using a separate configuration file. To create the
-configuration file, run the following command after updating:
-
-```sh
-./utils/setup.php --setup-website
-```
-
-### Update SQL code
-
-To update the SQL code to the leatest version run:
-
-```
-./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
-```
-
-## 3.4.0 -> 3.5.0
-
-### New Wikipedia/Wikidata importance tables
-
-The `wikipedia_*` tables have a new format that also includes references to
-Wikidata. You need to update the computation functions and the tables as
-follows:
-
-  * download the new Wikipedia tables as described in the import section
-  * reimport the tables: `./utils/setup.php --import-wikipedia-articles`
-  * update the functions: `./utils/setup.php --create-functions --enable-diff-updates`
-  * create a new lookup index:
-```sql
-CREATE INDEX idx_placex_wikidata
-  ON placex
-  USING BTREE ((extratags -> 'wikidata'))
-  WHERE extratags ? 'wikidata'
-    AND class = 'place'
-    AND osm_type = 'N'
-    AND rank_search < 26;
-```
-  * compute importance: `./utils/update.php --recompute-importance`
-
-The last step takes about 10 hours on the full planet.
-
-Remove one function (it will be recreated in the next step):
-
-```sql
-DROP FUNCTION create_country(hstore,character varying);
-```
-
-Finally, update all SQL functions:
-
-```sh
-./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
-```
-
-## 3.3.0 -> 3.4.0
-
-### Reorganisation of location_area_country table
-
-The table `location_area_country` has been optimized. You need to switch to the
-new format when you run updates. While updates are disabled, run the following
-SQL commands:
-
-```sql
-CREATE TABLE location_area_country_new AS
-  SELECT place_id, country_code, geometry FROM location_area_country;
-DROP TABLE location_area_country;
-ALTER TABLE location_area_country_new RENAME TO location_area_country;
-CREATE INDEX idx_location_area_country_geometry ON location_area_country USING GIST (geometry);
-CREATE INDEX idx_location_area_country_place_id ON location_area_country USING BTREE (place_id);
-```
-
-Finally, update all SQL functions:
-
-```sh
-./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
-```
-
-## 3.2.0 -> 3.3.0
-
-### New database connection string (DSN) format
-
-Previously database connection setting (`CONST_Database_DSN` in `settings/*.php`) had the format
-
-   * (simple) `pgsql://@/nominatim`
-   * (complex) `pgsql://johndoe:secret@machine1.domain.com:1234/db1`
-
-The new format is
-
-   * (simple) `pgsql:dbname=nominatim`
-   * (complex) `pgsql:dbname=db1;host=machine1.domain.com;port=1234;user=johndoe;password=secret`
-
-### Natural Earth country boundaries no longer needed as fallback
-
-```sql
-DROP TABLE country_naturalearthdata;
-```
-
-Finally, update all SQL functions:
-
-```sh
-./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
-```
-
-### Configurable Address Levels
-
-The new configurable address levels require a new table. Create it with the
-following command:
-
-```sh
-./utils/update.php --update-address-levels
-```
-
-## 3.1.0 -> 3.2.0
-
-### New reverse algorithm
-
-The reverse algorithm has changed and requires new indexes. Run the following
-SQL statements to create the indexes:
-
-```sql
-CREATE INDEX idx_placex_geometry_reverse_lookupPoint
-  ON placex
-  USING gist (geometry)
-  WHERE (name IS NOT null or housenumber IS NOT null or rank_address BETWEEN 26 AND 27)
-    AND class NOT IN ('railway','tunnel','bridge','man_made')
-    AND rank_address >= 26
-    AND indexed_status = 0
-    AND linked_place_id IS null;
-CREATE INDEX idx_placex_geometry_reverse_lookupPolygon
-  ON placex USING gist (geometry)
-  WHERE St_GeometryType(geometry) in ('ST_Polygon', 'ST_MultiPolygon')
-    AND rank_address between 4 and 25
-    AND type != 'postcode'
-    AND name is not null
-    AND indexed_status = 0
-    AND linked_place_id is null;
-CREATE INDEX idx_placex_geometry_reverse_placeNode
-  ON placex USING gist (geometry)
-  WHERE osm_type = 'N'
-    AND rank_search between 5 and 25
-    AND class = 'place'
-    AND type != 'postcode'
-    AND name is not null
-    AND indexed_status = 0
-    AND linked_place_id is null;
-```
-
-You also need to grant the website user access to the `country_osm_grid` table:
-
-```sql
-GRANT SELECT ON table country_osm_grid to "www-user";
-```
-
-Replace the `www-user` with the user name of your website server if necessary.
-
-You can now drop the unused indexes:
-
-```sql
-DROP INDEX idx_placex_reverse_geometry;
-```
-
-Finally, update all SQL functions:
-
-```sh
-./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
-```
-
-## 3.0.0 -> 3.1.0
-
-### Postcode Table
-
-A new separate table for artificially computed postcode centroids was introduced.
-Migration to the new format is possible but **not recommended**.
-
-Create postcode table and indexes, running the following SQL statements:
-
-```sql
-CREATE TABLE location_postcode
-  (place_id BIGINT, parent_place_id BIGINT, rank_search SMALLINT,
-   rank_address SMALLINT, indexed_status SMALLINT, indexed_date TIMESTAMP,
-   country_code varchar(2), postcode TEXT,
-   geometry GEOMETRY(Geometry, 4326));
-CREATE INDEX idx_postcode_geometry ON location_postcode USING GIST (geometry);
-CREATE UNIQUE INDEX idx_postcode_id ON location_postcode USING BTREE (place_id);
-CREATE INDEX idx_postcode_postcode ON location_postcode USING BTREE (postcode);
-GRANT SELECT ON location_postcode TO "www-data";
-DROP TYPE IF EXISTS nearfeaturecentr CASCADE;
-CREATE TYPE nearfeaturecentr AS (
-  place_id BIGINT,
-  keywords int[],
-  rank_address smallint,
-  rank_search smallint,
-  distance float,
-  isguess boolean,
-  postcode TEXT,
-  centroid GEOMETRY
-);
-```
-
-Add postcode column to `location_area` tables with SQL statement:
-
-```sql
-ALTER TABLE location_area ADD COLUMN postcode TEXT;
-```
-
-Then reimport the functions:
-
-```sh
-./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
-```
-
-Create appropriate triggers with SQL:
-
-```sql
-CREATE TRIGGER location_postcode_before_update BEFORE UPDATE ON location_postcode
-    FOR EACH ROW EXECUTE PROCEDURE postcode_update();
-```
-
-Finally populate the postcode table (will take a while):
-
-```sh
-./utils/setup.php --calculate-postcodes --index --index-noanalyse
-```
-
-This will create a working database. You may also delete the old artificial
-postcodes now. Note that this may be expensive and is not absolutely necessary.
-The following SQL statement will remove them:
-
-```sql
-DELETE FROM place_addressline a USING placex p
- WHERE a.address_place_id = p.place_id and p.osm_type = 'P';
-ALTER TABLE placex DISABLE TRIGGER USER;
-DELETE FROM placex WHERE osm_type = 'P';
-ALTER TABLE placex ENABLE TRIGGER USER;
-```

-and unpack it. You can use `nominatim-ui-x.x.x.tar.gz` or `nominatim-ui-x.x.x.zip`.

-Next you need to adapt the UI to your installation. Custom settings need to be
-put into `dist/theme/config.theme.js`. At a minimum you need to
-set `Nominatim_API_Endpoint` to point to your Nominatim installation:
-
-    cd nominatim-ui
-    echo "Nominatim_Config.Nominatim_API_Endpoint='https://myserver.org/nominatim/';" > dist/theme/config.theme.js
-
-For the full set of available settings, have a look at `dist/config.defaults.js`.
-
-Then you can just test it locally by spinning up a webserver in the `dist`
-directory. For example, with Python:
-
-    cd nominatim-ui/dist
-    python3 -m http.server 8765
-
-The website is now available at `http://localhost:8765`.
-
-## Forwarding searches to nominatim-ui
-
-Nominatim used to provide the search interface directly by itself when
-`format=html` was requested. For all endpoints except for `/reverse` and
-`/lookup` this even used to be the default.
-
-The following section describes how to set up Apache or nginx, so that your
-users are forwarded to nominatim-ui when they go to URL that formerly presented
-the UI.
-
-### Setting up forwarding in Nginx
-
-First of all make nominatim-ui available under `/ui` on your webserver:
-
-``` nginx
-server {
-
-    # Here is the Nominatim setup as described in the Installation section
-
-    location /ui/ {
-        alias <full path to the nominatim-ui directory>/dist/;
-        index index.html;
-    }
-}
-```
-
-Now we need to find out if a URL should be forwarded to the UI. Add the
-following `map` commands *outside* the server section:
-
-``` nginx
-# Inspect the format parameter in the query arguments. We are interested
-# if it is set to html or something else or if it is missing completely.
-map $args $format {
-    default                  default;
-    ~(^|&)format=html(&|$)   html;
-    ~(^|&)format=            other;
-}
-
-# Determine from the URI and the format parameter above if forwarding is needed.
-map $uri/$format $forward_to_ui {
-    default               1;   # The default is to forward.
-    ~^/ui                 0;   # If the URI point to the UI already, we are done.
-    ~/other$              0;   # An explicit non-html format parameter. No forwarding.
-    ~/reverse.*/default   0;   # Reverse and lookup assume xml format when
-    ~/lookup.*/default    0;   #   no format parameter is given. No forwarding.
-}
-```
-
-The `$forward_to_ui` parameter can now be used to conditionally forward the
-calls:
-
-```
-# When no endpoint is given, default to search.
-# Need to add a rewrite so that the rewrite rules below catch it correctly.
-rewrite ^/$ /search;
-
-location @php {
-    # fastcgi stuff..
-    if ($forward_to_ui) {
-        rewrite ^(/[^/]*) https://yourserver.com/ui$1.html redirect;
-    }
-}
-
-location ~ [^/]\.php(/|$) {
-    # fastcgi stuff..
-    if ($forward_to_ui) {
-        rewrite (.*).php https://yourserver.com/ui$1.html redirect;
-    }
-}
-```
-
-!!! warning
-    Be aware that the rewrite commands are slightly different for URIs with and
-    without the .php suffix.
-
-Reload nginx and the UI should be available.
-
-### Setting up forwarding in Apache
-
-First of all make nominatim-ui available in the `ui/` subdirectory where
-Nominatim is installed. For example, given you have set up an alias under
-`nominatim` like this:
-
-``` apache
-Alias /nominatim /home/vagrant/build/website
-```
-
-you need to insert the following rules for nominatim-ui before that alias:
-
-```
-<Directory "/home/vagrant/nominatim-ui/dist">
-  DirectoryIndex search.html
-  Require all granted
-</Directory>
-
-Alias /nominatim/ui /home/vagrant/nominatim-ui/dist
-```
-
-Replace `/home/vagrant/nominatim-ui` with the directory where you have cloned
-nominatim-ui.
-
-!!! important
-    The alias for nominatim-ui must come before the alias for the Nominatim
-    website directory.
-
-To set up forwarding, the Apache rewrite module is needed. Enable it with:
-
-``` sh
-sudo a2enmod rewrite
-```
-
-Then add rewrite rules to the `Directory` directive of the Nominatim website
-directory like this:
-
-``` apache
-<Directory "/home/vagrant/build/website">
-  Options FollowSymLinks MultiViews
-  AddType text/html   .php
-  Require all granted
-
-  RewriteEngine On
-
-  # This must correspond to the URL where nominatim can be found.
-  RewriteBase "/nominatim/"
-
-  # If no endpoint is given, then use search.
-  RewriteRule ^(/|$)   "search.php"
-
-  # If format-html is explicitly requested, forward to the UI.
-  RewriteCond %{QUERY_STRING} "format=html"
-  RewriteRule ^([^/]+)(.php)? ui/$1.html [R,END]
-
-  # If no format parameter is there then forward anything
-  # but /reverse and /lookup to the UI.
-  RewriteCond %{QUERY_STRING} "!format="
-  RewriteCond %{REQUEST_URI}  "!/lookup"
-  RewriteCond %{REQUEST_URI}  "!/reverse"
-  RewriteRule ^([^/]+)(.php)? ui/$1.html [R,END]
-</Directory>
-```
-
-Restart Apache and the UI should be available.

-# Updating the Database
-
-There are many different ways to update your Nominatim database.
-The following section describes how to keep it up-to-date using
-an [online replication service for OpenStreetMap data](https://wiki.openstreetmap.org/wiki/Planet.osm/diffs)
-For a list of other methods to add or update data see the output of
-`nominatim add-data --help`.
-
-!!! important
-    If you have configured a flatnode file for the import, then you
-    need to keep this flatnode file around for updates.
-
-### Installing the newest version of Pyosmium
-
-The replication process uses
-[Pyosmium](https://docs.osmcode.org/pyosmium/latest/updating_osm_data.html)
-to download update data from the server.
-It is recommended to install Pyosmium via pip.
-Run (as the same user who will later run the updates):
-
-```sh
-pip3 install --user osmium
-```
-
-### Setting up the update process
-
-Next the update process needs to be initialised. By default Nominatim is configured
-to update using the global minutely diffs.
-
-If you want a different update source you will need to add some settings
-to `.env`. For example, to use the daily country extracts
-diffs for Ireland from Geofabrik add the following:
-
-    # base URL of the replication service
-    NOMINATIM_REPLICATION_URL="https://download.geofabrik.de/europe/ireland-and-northern-ireland-updates"
-    # How often upstream publishes diffs (in seconds)
-    NOMINATIM_REPLICATION_UPDATE_INTERVAL=86400
-    # How long to sleep if no update found yet (in seconds)
-    NOMINATIM_REPLICATION_RECHECK_INTERVAL=900
-
-To set up the update process now run the following command:
-
-    nominatim replication --init
-
-It outputs the date where updates will start. Recheck that this date is
-what you expect.
-
-The `replication --init` command needs to be rerun whenever the replication
-service is changed.
-
-### Updating Nominatim
-
-Nominatim supports different modes how to retrieve the update data from the
-server. Which one you want to use depends on your exact setup and how often you
-want to retrieve updates.
-
-These instructions are for using a single source of updates. If you have
-imported multiple country extracts and want to keep them
-up-to-date, [Advanced installations section](Advanced-Installations.md)
-contains instructions to set up and update multiple country extracts.
-
-#### Continuous updates
-
-This is the easiest mode. Simply run the replication command without any
-parameters:
-
-    nominatim replication
-
-The update application keeps running forever and retrieves and applies
-new updates from the server as they are published.
-
-You can run this command as a simple systemd service. Create a service
-description like that in `/etc/systemd/system/nominatim-updates.service`:
-
-```
-[Unit]
-Description=Continuous updates of Nominatim
-
-[Service]
-WorkingDirectory=/srv/nominatim
-ExecStart=nominatim replication
-StandardOutput=append:/var/log/nominatim-updates.log
-StandardError=append:/var/log/nominatim-updates.error.log
-User=nominatim
-Group=nominatim
-Type=simple
-
-[Install]
-WantedBy=multi-user.target
-```
-
-Replace the `WorkingDirectory` with your project directory. Also adapt user
-and group names as required.
-
-Now activate the service and start the updates:
-
-```
-sudo systemctl daemon-reload
-sudo systemctl enable nominatim-updates
-sudo systemctl start nominatim-updates
-```
-
-#### One-time mode
-
-When the `--once` parameter is given, then Nominatim will download exactly one
-batch of updates and then exit. This one-time mode still respects the
-`NOMINATIM_REPLICATION_UPDATE_INTERVAL` that you have set. If according to
-the update interval no new data has been published yet, it will go to sleep
-until the next expected update and only then attempt to download the next batch.
-
-The one-time mode is particularly useful if you want to run updates continuously
-but need to schedule other work in between updates. For example, the main
-service at osm.org uses it, to regularly recompute postcodes -- a process that
-must not be run while updates are in progress. Its update script
-looks like this:
-
-```sh
-#!/bin/bash
-
-# Switch to your project directory.
-cd /srv/nominatim
-
-while true; do
-  nominatim replication --once
-  if [ -f "/srv/nominatim/schedule-maintenance" ]; then
-    rm /srv/nominatim/schedule-maintenance
-    nominatim refresh --postcodes
-  fi
-done
-```
-
-A cron job then creates the file `/srv/nominatim/schedule-maintenance` once per night.
-
-##### One-time mode with systemd
-
-You can run the one-time mode with a systemd timer & service.
-
-Create a timer description like `/etc/systemd/system/nominatim-updates.timer`:
-
-```
-[Unit]
-Description=Timer to start updates of Nominatim
-
-[Timer]
-OnActiveSec=2
-OnUnitActiveSec=1min
-Unit=nominatim-updates.service
-
-[Install]
-WantedBy=multi-user.target
-```
-
-And then a similar service definition: `/etc/systemd/system/nominatim-updates.service`:
-
-```
-[Unit]
-Description=Single updates of Nominatim
-
-[Service]
-WorkingDirectory=/srv/nominatim
-ExecStart=nominatim replication --once
-StandardOutput=append:/var/log/nominatim-updates.log
-StandardError=append:/var/log/nominatim-updates.error.log
-User=nominatim
-Group=nominatim
-Type=simple
-
-[Install]
-WantedBy=multi-user.target
-```
-
-Replace the `WorkingDirectory` with your project directory. Also adapt user and
-group names as required. `OnUnitActiveSec` defines how often the individual
-update command is run.
-
-Now activate the service and start the updates:
-
-```
-sudo systemctl daemon-reload
-sudo systemctl enable nominatim-updates.timer
-sudo systemctl start nominatim-updates.timer
-```
-
-You can stop future data updates, while allowing any current, in-progress
-update steps to finish, by running `sudo systemctl stop
-nominatim-updates.timer` and waiting until `nominatim-updates.service` isn't
-running (`sudo systemctl is-active nominatim-updates.service`). Current output
-from the update can be seen like above (`systemctl status
-nominatim-updates.service`).
-
-
-#### Catch-up mode
-
-With the `--catch-up` parameter, Nominatim will immediately try to download
-all changes from the server until the database is up-to-date. The catch-up mode
-still respects the parameter `NOMINATIM_REPLICATION_MAX_DIFF`. It downloads and
-applies the changes in appropriate batches until all is done.
-
-The catch-up mode is foremost useful to bring the database up to speed after the
-initial import. Give that the service usually is not in production at this
-point, you can temporarily be a bit more generous with the batch size and
-number of threads you use for the updates by running catch-up like this:
-
-```
-cd /srv/nominatim
-NOMINATIM_REPLICATION_MAX_DIFF=5000 nominatim replication --catch-up --threads 15
-```
-
-The catch-up mode is also useful when you want to apply updates at a lower
-frequency than what the source publishes. You can set up a cron job to run
-replication catch-up at whatever interval you desire.
-
-!!! hint
-    When running scheduled updates with catch-up, it is a good idea to choose
-    a replication source with an update frequency that is an order of magnitude
-    lower. For example, if you want to update once a day, use an hourly updated
-    source. This makes sure that you don't miss an entire day of updates when
-    the source is unexpectedly late to publish its update.
-
-    If you want to use the source with the same update frequency (e.g. a daily
-    updated source with daily updates), use the
-    continuous update mode. It ensures to re-request the newest update until it
-    is published.

-# Place details
-
-Show all details about a single place saved in the database.
-
-!!! warning
-    The details page exists for debugging only. You may not use it in scripts
-    or to automatically query details about a result.
-    See [Nominatim Usage Policy](https://operations.osmfoundation.org/policies/nominatim/).
-
-
-## Parameters
-
-The details API supports the following two request formats:
-
-``` xml
-https://nominatim.openstreetmap.org/details?osmtype=[N|W|R]&osmid=<value>&class=<value>
-```
-
-`osmtype` and `osmid` are required parameters. The type is one of node (N), way (W)
-or relation (R). The id must be a number. The `class` parameter is optional and
-allows to distinguish between entries, when the corresponding OSM object has more
-than one main tag. For example, when a place is tagged with `tourism=hotel` and
-`amenity=restaurant`, there will be two place entries in Nominatim, one for a
-restaurant, one for a hotel. You need to specify `class=tourism` or `class=amentity`
-to get exactly the one you want. If there are multiple places in the database
-but the `class` parameter is left out, then one of the places will be chosen
-at random and displayed.
-
-``` xml
-https://nominatim.openstreetmap.org/details?place_id=<value>
-```
-
-Place IDs are assigned sequentially during Nominatim data import. The ID
-for a place is different between Nominatim installation (servers) and
-changes when data gets reimported. Therefore it cannot be used as
-a permanent id and shouldn't be used in bug reports.
-
-
-Additional optional parameters are explained below.
-
-### Output format
-
-* `json_callback=<string>`
-
-Wrap JSON output in a callback function (JSONP) i.e. `<string>(<json>)`.
-
-* `pretty=[0|1]`
-
-Add indentation to make it more human-readable. (Default: 0)
-
-
-### Output details
-
-* `addressdetails=[0|1]`
-
-Include a breakdown of the address into elements. (Default: 0)
-
-* `keywords=[0|1]`
-
-Include a list of name keywords and address keywords (word ids). (Default: 0)
-
-* `linkedplaces=[0|1]`
-
-Include a details of places that are linked with this one. Places get linked
-together when they are different forms of the same physical object. Nominatim
-links two kinds of objects together: place nodes get linked with the
-corresponding administrative boundaries. Waterway relations get linked together with their
-members.
-(Default: 1)
-
-* `hierarchy=[0|1]`
-
-Include details of places lower in the address hierarchy. (Default: 0)
-
-* `group_hierarchy=[0|1]`
-
-For JSON output will group the places by type. (Default: 0)
-
-* `polygon_geojson=[0|1]`
-
-Include geometry of result. (Default: 0)
-
-### Language of results
-
-* `accept-language=<browser language string>`
-
-Preferred language order for showing result, overrides the value
-specified in the "Accept-Language" HTTP header.
-Either use a standard RFC2616 accept-language string or a simple
-comma-separated list of language codes.

-# Frequently Asked Questions
-
-## API Results
-
-#### 1. The address of my search results contains far-away places that don't belong there.
-
-Nominatim computes the address from two sources in the OpenStreetMap data:
-from administrative boundaries and from place nodes. Boundaries are the more
-useful source. They precisely describe an area. So it is very clear for
-Nominatim if a point belongs to an area or not. Place nodes are more complicated.
-These are only points without any precise extent. So Nominatim has to take a
-guess and assume that an address belongs to the closest place node it can find.
-In an ideal world, Nominatim would not need the place nodes but there are
-many places on earth where there are no precise boundaries available for
-all parts that make up an address. This is in particular true for the more
-local address parts, like villages and suburbs. Therefore it is not possible
-to completely dismiss place nodes. And sometimes they sneak in where they
-don't belong.
-
-As a OpenStreetMap mapper, you can improve the situation in two ways: if you
-see a place node for which already an administrative area exists, then you
-should _link_ the two by adding the node with a 'label' role to the boundary
-relation. If there is no administrative area, you can add the approximate
-extent of the place and tag it place=<something> as well.
-
-#### 2. When doing reverse search, the address details have parts that don't contain the point I was looking up.
-
-There is a common misconception how the reverse API call works in Nominatim.
-Reverse does not give you the address of the point you asked for. Reverse
-returns the closest object to the point you asked for and then returns the
-address of that object. Now, if you are close to a border, then the closest
-object may be across that border. When Nominatim then returns the address,
-it contains the county/state/country across the border.
-
-#### 3. I get different counties/states/countries when I change the zoom parameter in the reverse query. How is that possible?
-
-This is basically the same problem as in the previous answer.
-The zoom level influences at which [search rank](../customize/Ranking.md#search-rank) Nominatim starts looking
-for the closest object. So the closest house number maybe on one side of the
-border while the closest street is on the other. As the address details contain
-the address of the closest object found, you might sometimes get one result,
-sometimes the other for the closest point.
-
-#### 4. Can you return the continent?
-
-Nominatim assigns each map feature one country. Those outside any administrative
-boundaries are assigned a special no-country. Continents or other super-national
-administrations (e.g. European Union, NATO, Custom unions) are not supported,
-see also [Administrative Boundary](https://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative#Super-national_administrations).
-
-#### 5. Can you return the timezone?
-
-See this separate OpenStreetMap-based project [Timezone Boundary Builder](https://github.com/evansiroky/timezone-boundary-builder).
-
-#### 6. I want to download a list of streets/restaurants of a city/region
-
-The [Overpass API](https://wiki.openstreetmap.org/wiki/Overpass_API) is more
-suited for these kinds of queries.
-
-That said if you installed your own Nominatim instance you can use the
-`nominatim export` PHP script as basis to return such lists.
-
-#### 7. My result has a wrong postcode. Where does it come from?
-
-Most places in OSM don't have a postcode, so Nominatim tries to interpolate
-one. It first look at all the places that make up the address of the place.
-If one of them has a postcode defined, this is the one to be used. When
-none of the address parts has a postcode either, Nominatim interpolates one
-from the surrounding objects. If the postcode is for your result is one, then
-most of the time there is an OSM object with the wrong postcode nearby.
-
-To find the bad postcode, go to
-[https://nominatim.openstreetmap.org](https://nominatim.openstreetmap.org)
-and search for your place. When you have found it, click on the 'details' link
-under the result to go to the details page. There is a field 'Computed Postcode'
-which should display the bad postcode. Click on the 'how?' link. A small
-explanation text appears. It contains a link to a query for Overpass Turbo.
-Click on that and you get a map with all places in the area that have the bad
-postcode. If none is displayed, zoom the map out a bit and then click on 'Run'.
-
-Now go to [OpenStreetMap](https://openstreetmap.org) and fix the error you
-have just found. It will take at least a day for Nominatim to catch up with
-your data fix. Sometimes longer, depending on how much editing activity is in
-the area.

-
-## JSON
-
-The JSON format returns an array of places (for search and lookup) or
-a single place (for reverse) of the following format:

-
-
-## Notes on field values
-
-### place_id is not a persistent id
-
-The `place_id` is an internal identifier that is assigned data is imported
-into a Nominatim database. The same OSM object will have a different value
-on another server. It may even change its ID on the same server when it is
-removed and reimported while updating the database with fresh OSM data.
-It is thus not useful to treat it as permanent for later use.
-
-The combination `osm_type`+`osm_id` is slightly better but remember in
-OpenStreetMap mappers can delete, split, recreate places (and those
-get a new `osm_id`), there is no link between those old and new ids.
-Places can also change their meaning without changing their `osm_id`,
-e.g. when a restaurant is retagged as supermarket. For a more in-depth
-discussion see [Permanent ID](https://wiki.openstreetmap.org/wiki/Permanent_ID).
-
-If you need an ID that is consistent over multiple installations of Nominatim,
-then you should use the combination of `osm_type`+`osm_id`+`class`.
-
-### OSM reference
-
-Nominatim may sometimes return special objects that do not correspond directly
-to an object in OpenStreetMap. These are:
-
-* **Postcodes**. Nominatim returns an postcode point created from all mapped
-  postcodes of the same name. The class and type of these object is `place=postcdode`.
-  No `osm_type` and `osm_id` are included in the result.
-* **Housenumber interpolations**. Nominatim returns a single interpolated
-  housenumber from the interpolation way. The class and type are `place=house`
-  and `osm_type` and `osm_id` correspond to the interpolation way in OSM.
-* **TIGER housenumber.** Nominatim returns a single interpolated housenumber
-  from the TIGER data. The class and type are `place=house`
-  and `osm_type` and `osm_id` correspond to the street mentioned in the result.
-
-Please note that the `osm_type` and `osm_id` returned may be changed in the
-future. You should not expect to only find `node`, `way` and `relation` for
-the type.
-
-### boundingbox
-
-Comma separated list of min latitude, max latitude, min longitude, max longitude.
-The whole planet would be `-90,90,-180,180`.
-
-Can be used to pan and center the map on the result, for example with leafletjs
-mapping library
-`map.fitBounds([[bbox[0],bbox[2]],[bbox[1],bbox[3]]], {padding: [20, 20], maxzoom: 16});`
-
-Bounds crossing the antimeridian have a min latitude -180 and max latitude 180,
-essentially covering the entire planet
-(see [issue 184](https://github.com/openstreetmap/Nominatim/issues/184)).
-
-### addressdetails
-
-Address details in the xml and json formats return a list of names together
-with a designation label. Per default the following labels may appear:
-
- * continent
- * country, country_code
- * region, state, state_district, county, ISO3166-2-lvl<admin_level>
- * municipality, city, town, village
- * city_district, district, borough, suburb, subdivision
- * hamlet, croft, isolated_dwelling
- * neighbourhood, allotments, quarter
- * city_block, residential, farm, farmyard, industrial, commercial, retail
- * road
- * house_number, house_name
- * emergency, historic, military, natural, landuse, place, railway,
-   man_made, aerialway, boundary, amenity, aeroway, club, craft, leisure,
-   office, mountain_pass, shop, tourism, bridge, tunnel, waterway
- * postcode
-
-They roughly correspond to the classification of the OpenStreetMap data
-according to either the `place` tag or the main key of the object.

-### Nominatim API
-
-Nominatim indexes named (or numbered) features within the OpenStreetMap (OSM) dataset and a subset of other unnamed features (pubs, hotels, churches, etc).
-
-Its API has the following endpoints for querying the data:
-
- * __[/search](Search.md)__ - search OSM objects by name or type
- * __[/reverse](Reverse.md)__ - search OSM object by their location
- * __[/lookup](Lookup.md)__ - look up address details for OSM objects by their ID
- * __[/status](Status.md)__ - query the status of the server
- * __/deletable__ - list objects that have been deleted in OSM but are held
-                    back in Nominatim in case the deletion was accidental
- * __/polygons__ - list of broken polygons detected by Nominatim
- * __[/details](Details.md)__ - show internal details for an object (for debugging only)

-# Reverse Geocoding
-
-Reverse geocoding generates an address from a latitude and longitude.
-
-## How it works
-
-The reverse geocoding API does not exactly compute the address for the
-coordinate it receives. It works by finding the closest suitable OSM object
-and returning its address information. This may occasionally lead to
-unexpected results.
-
-First of all, Nominatim only includes OSM objects in
-its index that are suitable for searching. Small, unnamed paths for example
-are missing from the database and can therefore not be used for reverse
-geocoding either.
-
-The other issue to be aware of is that the closest OSM object may not always
-have a similar enough address to the coordinate you were requesting. For
-example, in dense city areas it may belong to a completely different street.
-
-
-## Parameters
-
-The main format of the reverse API is
-
-```
-https://nominatim.openstreetmap.org/reverse?lat=<value>&lon=<value>&<params>
-```
-
-where `lat` and `lon` are latitude and longitude of a coordinate in WGS84
-projection. The API returns exactly one result or an error when the coordinate
-is in an area with no OSM data coverage.
-
-Additional parameters are accepted as listed below.
-
-!!! warning "Deprecation warning"
-    The reverse API used to allow address lookup for a single OSM object by
-    its OSM id. This use is now deprecated. Use the [Address Lookup API](Lookup.md)
-    instead.
-
-### Output format
-
-* `format=[xml|json|jsonv2|geojson|geocodejson]`
-
-See [Place Output Formats](Output.md) for details on each format. (Default: xml)
-
-* `json_callback=<string>`
-
-Wrap JSON output in a callback function ([JSONP](https://en.wikipedia.org/wiki/JSONP)) i.e. `<string>(<json>)`.
-Only has an effect for JSON output formats.
-
-### Output details
-
-* `addressdetails=[0|1]`
-
-Include a breakdown of the address into elements. (Default: 1)
-
-
-* `extratags=[0|1]`
-
-Include additional information in the result if available,
-e.g. wikipedia link, opening hours. (Default: 0)
-
-
-* `namedetails=[0|1]`
-
-Include a list of alternative names in the results. These may include
-language variants, references, operator and brand. (Default: 0)
-
-
-### Language of results
-
-* `accept-language=<browser language string>`
-
-Preferred language order for showing search results, overrides the value

-# Search queries
-
-The search API allows you to look up a location from a textual description
-or address. Nominatim supports structured and free-form search queries.
-
-The search query may also contain
-[special phrases](https://wiki.openstreetmap.org/wiki/Nominatim/Special_Phrases)
-which are translated into specific OpenStreetMap (OSM) tags (e.g. Pub => `amenity=pub`).
-This can be used to narrow down the kind of objects to be returned.
-
-!!! warning
-    Special phrases are not suitable to query all objects of a certain type in an
-    area. Nominatim will always just return a collection of the best matches. To
-    download OSM data by object type, use the [Overpass API](https://overpass-api.de/).
-
-## Parameters
-
-The search API has the following format:
-
-```
-   https://nominatim.openstreetmap.org/search?<params>
-```
-
-The search term may be specified with two different sets of parameters:
-
-* `q=<query>`
-
-    Free-form query string to search for.
-    Free-form queries are processed first left-to-right and then right-to-left if that fails. So you may search for
-    [pilkington avenue, birmingham](https://nominatim.openstreetmap.org/search?q=pilkington+avenue,birmingham) as well as for
-    [birmingham, pilkington avenue](https://nominatim.openstreetmap.org/search?q=birmingham,+pilkington+avenue).
-    Commas are optional, but improve performance by reducing the complexity of the search.
-
-
-* `street=<housenumber> <streetname>`
-* `city=<city>`
-* `county=<county>`
-* `state=<state>`
-* `country=<country>`
-* `postalcode=<postalcode>`
-
-    Alternative query string format split into several parameters for structured requests.
-    Structured requests are faster but are less robust against alternative
-    OSM tagging schemas. **Do not combine with** `q=<query>` **parameter**.
-
-Both query forms accept the additional parameters listed below.
-
-### Output format
-
-* `format=[xml|json|jsonv2|geojson|geocodejson]`
-
-See [Place Output Formats](Output.md) for details on each format. (Default: jsonv2)
-
-!!! note
-    The Nominatim service at
-    [https://nominatim.openstreetmap.org](https://nominatim.openstreetmap.org)
-    has a different default behaviour for historical reasons. When the
-    `format` parameter is omitted, the request will be forwarded to the Web UI.
-
-* `json_callback=<string>`
-
-Wrap JSON output in a callback function ([JSONP](https://en.wikipedia.org/wiki/JSONP)) i.e. `<string>(<json>)`.
-Only has an effect for JSON output formats.
-
-### Output details
-
-* `addressdetails=[0|1]`
-
-Include a breakdown of the address into elements. (Default: 0)
-
-
-* `extratags=[0|1]`
-
-Include additional information in the result if available,
-e.g. wikipedia link, opening hours. (Default: 0)
-
-
-* `namedetails=[0|1]`
-
-Include a list of alternative names in the results. These may include
-language variants, references, operator and brand. (Default: 0)
-
-
-### Language of results
-
-* `accept-language=<browser language string>`
-
-Preferred language order for showing search results, overrides the value
-specified in the ["Accept-Language" HTTP header](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept-Language).
-Either use a standard RFC2616 accept-language string or a simple
-comma-separated list of language codes.
-
-### Result limitation
-
-* `countrycodes=<countrycode>[,<countrycode>][,<countrycode>]...`
-
-Limit search results to one or more countries. `<countrycode>` must be the
-[ISO 3166-1alpha2](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2) code,
-e.g. `gb` for the United Kingdom, `de` for Germany.
-
-Each place in Nominatim is assigned to one country code based
-on OSM country boundaries. In rare cases a place may not be in any country
-at all, for example, in international waters.
-
-* `exclude_place_ids=<place_id,[place_id],[place_id]`
-
-If you do not want certain OSM objects to appear in the search
-result, give a comma separated list of the `place_id`s you want to skip.
-This can be used to retrieve additional search results. For example, if a
-previous query only returned a few results, then including those here would
-cause the search to return other, less accurate, matches (if possible).
-
-
-* `limit=<integer>`
-
-Limit the number of returned results. (Default: 10, Maximum: 50)
-
-
-* `viewbox=<x1>,<y1>,<x2>,<y2>`
-
-The preferred area to find search results. Any two corner points of the box
-are accepted as long as they span a real box. `x` is longitude,
-`y` is latitude.
-
-
-* `bounded=[0|1]`
-
-When a viewbox is given, restrict the result to items contained within that
-viewbox (see above). When `viewbox` and `bounded=1` are given, an amenity
-only search is allowed. Give the special keyword for the amenity in square
-brackets, e.g. `[pub]` and a selection of objects of this type is returned.
-There is no guarantee that the result is complete. (Default: 0)
-
-
-### Polygon output
-
-* `polygon_geojson=1`
-* `polygon_kml=1`
-* `polygon_svg=1`
-* `polygon_text=1`
-
-Output geometry of results as a GeoJSON, KML, SVG or WKT. Only one of these
-options can be used at a time. (Default: 0)
-
-* `polygon_threshold=0.0`
-
-Return a simplified version of the output geometry. The parameter is the
-tolerance in degrees with which the geometry may differ from the original
-geometry. Topology is preserved in the result. (Default: 0.0)
-
-### Other
-
-* `email=<valid email address>`
-
-If you are making large numbers of request please include an appropriate email
-address to identify your requests. See Nominatim's [Usage Policy](https://operations.osmfoundation.org/policies/nominatim/) for more details.
-
-* `dedupe=[0|1]`
-
-Sometimes you have several objects in OSM identifying the same place or
-object in reality. The simplest case is a street being split into many
-different OSM ways due to different characteristics. Nominatim will
-attempt to detect such duplicates and only return one match unless
-this parameter is set to 0. (Default: 1)
-
-* `debug=[0|1]`
-
-Output assorted developer debug information. Data on internals of Nominatim's
-"Search Loop" logic, and SQL queries. The output is (rough) HTML format.
-This overrides the specified machine readable format. (Default: 0)
-

-# Customizing Per-Country Data
-
-Whenever an OSM is imported into Nominatim, the object is first assigned
-a country. Nominatim can use this information to adapt various aspects of
-the address computation to the local customs of the country. This section
-explains how country assignment works and the principal per-country
-localizations.
-
-## Country assignment
-
-Countries are assigned on the basis of country data from the OpenStreetMap
-input data itself. Countries are expected to be tagged according to the
-[administrative boundary schema](https://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative):
-a OSM relation with `boundary=administrative` and `admin_level=2`. Nominatim
-uses the country code to distinguish the countries.
-
-If there is no country data available for a point, then Nominatim uses the
-fallback data imported from `data/country_osm_grid.sql.gz`. This was computed
-from OSM data as well but is guaranteed to cover all countries.
-
-Some OSM objects may also be located outside any country, for example a buoy
-in the middle of the ocean. These object do not get any country assigned and
-get a default treatment when it comes to localized handling of data.
-
-## Per-country settings
-
-### Global country settings
-
-The main place to configure settings per country is the file
-`settings/country_settings.yaml`. This file has one section per country that
-is recognised by Nominatim. Each section is tagged with the country code
-(in lower case) and contains the different localization information. Only
-countries which are listed in this file are taken into account for computations.
-
-For example, the section for Andorra looks like this:
-
-```
-    partition: 35
-    languages: ca
-    names: !include country-names/ad.yaml
-    postcode:
-      pattern: "(ddd)"
-      output: AD\1
-```
-
-The individual settings are described below.
-
-#### `partition`
-
-Nominatim internally splits the data into multiple tables to improve
-performance. The partition number tells Nominatim into which table to put
-the country. This is purely internal management and has no effect on the
-output data.
-
-The default is to have one partition per country.
-
-#### `languages`
-
-A comma-separated list of ISO-639 language codes of default languages in the
-country. These are the languages used in name tags without a language suffix.
-Note that this is not necessarily the same as the list of official languages
-in the country. There may be officially recognised languages in a country
-which are only ever used in name tags with the appropriate language suffixes.
-Conversely, a non-official language may appear a lot in the name tags, for
-example when used as an unofficial Lingua Franca.
-
-List the languages in order of frequency of appearance with the most frequently
-used language first. It is not recommended to add languages when there are only
-very few occurrences.
-
-If only one language is listed, then Nominatim will 'auto-complete' the
-language of names without an explicit language-suffix.
-
-#### `names`
-
-List of names of the country and its translations. These names are used as
-a baseline. It is always possible to search countries by the given names, no
-matter what other names are in the OSM data. They are also used as a fallback
-when a needed translation is not available.
-
-!!! Note
-    The list of names per country is currently fairly large because Nominatim
-    supports translations in many languages per default. That is why the
-    name lists have been separated out into extra files. You can find the
-    name lists in the file `settings/country-names/<country code>.yaml`.
-    The names section in the main country settings file only refers to these
-    files via the special `!include` directive.
-
-#### `postcode`
-
-Describes the format of the postcode that is in use in the country.
-
-When a country has no official postcodes, set this to no. Example:
-
-```
-ae:
-    postcode: no
-```
-
-When a country has a postcode, you need to state the postcode pattern and
-the default output format. Example:
-
-```
-bm:
-    postcode:
-      pattern: "(ll)[ -]?(dd)"
-      output: \1 \2
-```
-
-The **pattern** is a regular expression that describes the possible formats
-accepted as a postcode. The pattern follows the standard syntax for
-[regular expressions in Python](https://docs.python.org/3/library/re.html#regular-expression-syntax)
-with two extra shortcuts: `d` is a shortcut for a single digit([0-9])
-and `l` for a single ASCII letter ([A-Z]).
-
-Use match groups to indicate groups in the postcode that may optionally be
-separated with a space or a hyphen.
-
-For example, the postcode for Bermuda above always consists of two letters
-and two digits. They may optionally be separated by a space or hyphen. That
-means that Nominatim will consider `AB56`, `AB 56` and `AB-56` spelling variants
-for one and the same postcode.
-
-Never add the country code in front of the postcode pattern. Nominatim will
-automatically accept variants with a country code prefix for all postcodes.
-
-The **output** field is an optional field that describes what the canonical
-spelling of the postcode should be. The format is the
-[regular expression expand syntax](https://docs.python.org/3/library/re.html#re.Match.expand) referring back to the bracket groups in the pattern.
-
-Most simple postcodes only have one spelling variant. In that case, the
-**output** can be omitted. The postcode will simply be used as is.
-
-In the Bermuda example above, the canonical spelling would be to have a space
-between letters and digits.
-
-!!! Warning
-    When your postcode pattern covers multiple variants of the postcode, then
-    you must explicitly state the canonical output or Nominatim will not
-    handle the variations correctly.
-
-### Other country-specific configuration
-
-There are some other configuration files where you can set localized settings
-according to the assigned country. These are:

-## Configuring the Import
-
-Which OSM objects are added to the database and which of the tags are used
-can be configured via the import style configuration file. This
-is a JSON file which contains a list of rules which are matched against every
-tag of every object and then assign the tag its specific role.
-
-The style to use is given by the `NOMINATIM_IMPORT_STYLE` configuration
-option. There are a number of default styles, which are explained in detail
-in the [Import section](../admin/Import.md#filtering-imported-data). These
-standard styles may be referenced by their name.
-
-You can also create your own custom style. Put the style file into your
-project directory and then set `NOMINATIM_IMPORT_STYLE` to the name of the file.
-It is always recommended to start with one of the standard styles and customize
-those. You find the standard styles under the name `import-<stylename>.style`
-in the standard Nominatim configuration path (usually `/etc/nominatim` or
-`/usr/local/etc/nominatim`).
-
-The remainder of the page describes the format of the file.
-
-### Configuration Rules
-
-A single rule looks like this:
-
-```json
-{
-    "keys" : ["key1", "key2", ...],
-    "values" : {
-        "value1" : "prop",
-        "value2" : "prop1,prop2"
-    }
-}
-```
-
-A rule first defines a list of keys to apply the rule to. This is always a list
-of strings. The string may have four forms. An empty string matches against
-any key. A string that ends in an asterisk `*` is a prefix match and accordingly
-matches against any key that starts with the given string (minus the `*`). A
-suffix match can be defined similarly with a string that starts with a `*`. Any
-other string constitutes an exact match.
-
-The second part of the rules defines a list of values and the properties that
-apply to a successful match. Value strings may be either empty, which
-means that they match any value, or describe an exact match. Prefix
-or suffix matching of values is not possible.
-
-For a rule to match, it has to find a valid combination of keys and values. The
-resulting property is that of the matched values.
-
-The rules in a configuration file are processed sequentially and the first
-match for each tag wins.
-
-A rule where key and value are the empty string is special. This defines the
-fallback when none of the rules match. The fallback is always used as a last
-resort when nothing else matches, no matter where the rule appears in the file.
-Defining multiple fallback rules is not allowed. What happens in this case,
-is undefined.
-
-### Tag Properties
-
-One or more of the following properties may be given for each tag:
-
-* `main`
-
-    A principal tag. A new row will be added for the object with key and value
-    as `class` and `type`.
-
-* `with_name`
-
-    When the tag is a principal tag (`main` property set): only really add a new
-    row, if there is any name tag found (a reference tag is not sufficient, see
-    below).
-
-* `with_name_key`
-
-    When the tag is a principal tag (`main` property set): only really add a new
-    row, if there is also a name tag that matches the key of the principal tag.
-    For example, if the main tag is `bridge=yes`, then it will only be added as
-    an extra row, if there is a tag `bridge:name[:XXX]` for the same object.
-    If this property is set, all other names that are not domain-specific are
-    ignored.
-
-* `fallback`
-
-    When the tag is a principal tag (`main` property set): only really add a new
-    row, when no other principal tags for this object have been found. Only one
-    fallback tag can win for an object.
-
-* `operator`
-
-    When the tag is a principal tag (`main` property set): also include the
-    `operator` tag in the list of names. This is a special construct for an
-    out-dated tagging practise in OSM. Fuel stations and chain restaurants
-    in particular used to have the name of the chain tagged as `operator`.
-    These days the chain can be more commonly found in the `brand` tag but
-    there is still enough old data around to warrant this special case.
-
-* `name`
-
-    Add tag to the list of names.
-
-* `ref`
-
-    Add tag to the list of names as a reference. At the moment this only means
-    that the object is not considered to be named for `with_name`.
-
-* `address`
-
-    Add tag to the list of address tags. If the tag starts with `addr:` or
-    `is_in:`, then this prefix is cut off before adding it to the list.
-
-* `postcode`
-
-    Add the value as a postcode to the address tags. If multiple tags are
-    candidate for postcodes, one wins out and the others are dropped.
-
-* `country`
-
-    Add the value as a country code to the address tags. The value must be a
-    two letter country code, otherwise it is ignored. If there are multiple
-    tags that match, then one wins out and the others are dropped.
-
-* `house`
-
-    If no principle tags can be found for the object, still add the object with
-    `class`=`place` and `type`=`house`. Use this for address nodes that have no
-    other function.
-
-* `interpolation`
-
-    Add this object as an address interpolation (appears as `class`=`place` and
-    `type`=`houses` in the database).
-
-* `extra`
-
-    Add tag to the list of extra tags.
-
-* `skip`
-
-    Skip the tag completely. Useful when a custom default fallback is defined
-    or to define exceptions to rules.
-
-A rule can define as many of these properties for one match as it likes. For
-example, if the property is `"main,extra"` then the tag will open a new row
-but also have the tag appear in the list of extra tags.
-
-### Changing the Style of Existing Databases
-
-There is normally no issue changing the style of a database that is already
-imported and now kept up-to-date with change files. Just be aware that any
-change in the style applies to updates only. If you want to change the data
-that is already in the database, then a reimport is necessary.

-## Importance
-
-Search requests can yield multiple results which match equally well with
-the original query. In such case Nominatim needs to order the results
-according to a different criterion: importance. This is a measure for how
-likely it is that a user will search for a given place. This section explains
-the sources Nominatim uses for computing importance of a place and how to
-customize them.
-
-### How importance is computed
-
-The main value for importance is derived from page ranking values for Wikipedia
-pages for a place. For places that do not have their own
-Wikipedia page, a formula is used that derives a static importance from the
-places [search rank](../customize/Ranking.md#search-rank).
-
-In a second step, a secondary importance value is added which is meant to
-represent how well-known the general area is where the place is located. It
-functions as a tie-breaker between places with very similar primary
-importance values.
-
-nominatim.org has preprocessed importance tables for the
-[primary Wikipedia rankings](https://nominatim.org/data/wikimedia-importance.sql.gz)
-and for a secondary importance based on the number of tile views on openstreetmap.org.
-
-### Customizing secondary importance
-
-The secondary importance is implemented as a simple
-[Postgis raster](https://postgis.net/docs/raster.html) table, where Nominatim
-looks up the value for the coordinates of the centroid of a place. You can
-provide your own secondary importance raster in form of an SQL file named
-`secondary_importance.sql.gz` in your project directory.
-
-The SQL file needs to drop and (re)create a table `secondary_importance` which
-must as a minimum contain a column `rast` of type `raster`. The raster must
-be in EPSG:4326 and contain 16bit unsigned ints
-(`raster_constraint_pixel_types(rast) = '{16BUI}'). Any other columns in the
-table will be ignored. You must furthermore create an index as follows:
-
-```
-CREATE INDEX ON secondary_importance USING gist(ST_ConvexHull(gist))
-```
-
-The following raster2pgsql command will create a table that conforms to
-the requirements:
-

-# External postcode data
-
-Nominatim creates a table of known postcode centroids during import. This table
-is used for searches of postcodes and for adding postcodes to places where the
-OSM data does not provide one. These postcode centroids are mainly computed
-from the OSM data itself. In addition, Nominatim supports reading postcode
-information from an external CSV file, to supplement the postcodes that are
-missing in OSM.
-
-To enable external postcode support, simply put one CSV file per country into
-your project directory and name it `<CC>_postcodes.csv`. `<CC>` must be the
-two-letter country code for which to apply the file. The file may also be
-gzipped. Then it must be called `<CC>_postcodes.csv.gz`.
-
-The CSV file must use commas as a delimiter and have a header line. Nominatim
-expects three columns to be present: `postcode`, `lat` and `lon`. All other
-columns are ignored. `lon` and `lat` must describe the x and y coordinates of the
-postcode centroids in WGS84.
-
-The postcode files are loaded only when there is data for the given country
-in your database. For example, if there is a `us_postcodes.csv` file in your
-project directory but you import only an excerpt of Italy, then the US postcodes
-will simply be ignored.
-
-As a rule, the external postcode data should be put into the project directory
-**before** starting the initial import. Still, you can add, remove and update the
-external postcode data at any time. Simply
-run:
-
-```
-nominatim refresh --postcodes
-```
-
-to make the changes visible in your database. Be aware, however, that the changes
-only have an immediate effect on searches for postcodes. Postcodes that were
-added to places are only updated, when they are reindexed. That usually happens
-only during replication updates.

-# Place Ranking in Nominatim
-
-Nominatim uses two metrics to rank a place: search rank and address rank.
-This chapter explains what place ranking means and how it can be customized.
-
-## Search rank
-
-The search rank describes the extent and importance of a place. It is used
-when ranking search results. Simply put, if there are two results for a
-search query which are otherwise equal, then the result with the _lower_
-search rank will be appear higher in the result list.
-
-Search ranks are not so important these days because many well-known
-places use the Wikipedia importance ranking instead.
-
-The following table gives an overview of the kind of features that Nominatim
-expects for each rank:
-
-rank   | typical place types             | extent
--------|---------------------------------|-------
-1-3    | oceans, continents              | -
-4      | countries                       | -
-5-9    | states, regions, provinces      | -
-10-12  | counties                        | -
-13-16  | cities, municipalities, islands | 15 km
-17-18  | towns, boroughs                 | 4 km
-19     | villages, suburbs               | 2 km
-20     | hamlets, farms, neighbourhoods  |  1 km
-21-25  | isolated dwellings, city blocks | 500 m
-
-The extent column describes how far a feature is assumed to reach when it
-is mapped only as a point. Larger features like countries and states are usually
-available with their exact area in the OpenStreetMap data. That is why no extent
-is given.
-
-## Address rank
-
-The address rank describes where a place shows up in an address hierarchy.
-Usually only administrative boundaries and place nodes and areas are
-eligible to be part of an address. Places that should not appear in the
-address must have an address rank of 0.
-
-The following table gives an overview how ranks are mapped to address parts:
-
- rank        | address part
--------------|-------------
- 1-3         | _unused_
- 4           | country
- 5-9         | state
- 10-12       | county
- 13-16       | city
- 17-21       | suburb

-
-The country rank 4 usually doesn't show up in the address parts of an object.
-The country is determined indirectly from the country code.
-
-Ranks 5-24 can be assigned more or less freely. They make up the major part
-of the address.
-
-Rank 25 is also an addressing rank but it is special because while it can be
-the parent to a POI with an addr:place of the same name, it cannot be a parent
-to streets. Use it for place features that are technically on the same level
-as a street (e.g. squares, city blocks) or for places that should not normally
-appear in an address unless explicitly tagged so (e.g place=locality which
-should be uninhabited and as such not addressable).
-
-The street ranks 26 and 27 are handled slightly differently. Only one object
-from these ranks shows up in an address.
-
-For POI level objects like shops, buildings or house numbers always use rank 30.
-Ranks 28 is reserved for house number interpolations. 29 is for internal use
-only.
-
-## Rank configuration
-
-Search and address ranks are assigned to a place when it is first imported
-into the database. There are a few hard-coded rules for the assignment:
-
- * postcodes follow special rules according to their length
- * boundaries that are not areas and railway=rail are dropped completely
- * the following are always search rank 30 and address rank 0:
-    * highway nodes
-    * landuse that is not an area
-
-Other than that, the ranks can be freely assigned via the JSON file according
-to their type and the country they are in. The name of the config file to be
-used can be changed with the setting `NOMINATIM_ADDRESS_LEVEL_CONFIG`.
-
-The address level configuration must consist of an array of configuration
-entries, each containing a tag definition and an optional country array:
-
-```
-[ {
-    "tags" : {
-      "place" : {
-        "county" : 12,
-        "city" : 16,
-      },
-      "landuse" : {
-        "residential" : 22,
-        "" : 30
-      }
-    }
-  },
-  {
-    "countries" : [ "ca", "us" ],
-    "tags" : {
-      "boundary" : {
-        "administrative8" : 18,
-        "administrative9" : 20
-      },
-      "landuse" : {
-        "residential" : [22, 0]
-      }
-    }
-  }
-]
-```
-
-The `countries` field contains a list of countries (as ISO 3166-1 alpha 2 code)
-for which the definition applies. When the field is omitted, then the
-definition is used as a fallback, when nothing more specific for a given
-country exists.
-
-`tags` contains the ranks for key/value pairs. The ranks can be either a
-single number, in which case they are the search and address rank, or an array
-of search and address rank (in that order). The value may be left empty.
-Then the rank is used when no more specific value is found for the given
-key.
-
-Countries and key/value combination may appear in multiple definitions. Just
-make sure that each combination of country/key/value appears only once per
-file. Otherwise the import will fail with a UNIQUE INDEX constraint violation
-on import.

-be used with Nominatim.
-
-# Configuring Nominatim
-
-Nominatim uses [dotenv](https://github.com/theskumar/python-dotenv) to manage
-its configuration settings. There are two means to set configuration
-variables: through an `.env` configuration file or through an environment
-variable.
-
-The `.env` configuration file needs to be placed into the
-[project directory](../admin/Import.md#creating-the-project-directory). It
-must contain configuration parameters in `<parameter>=<value>` format.
-Please refer to the dotenv documentation for details.
-
-The configuration options may also be set in the form of shell environment
-variables. This is particularly useful, when you want to temporarily change
-a configuration option. For example, to force the replication serve to
-download the next change, you can temporarily disable the update interval:
-
-    NOMINATIM_REPLICATION_UPDATE_INTERVAL=0 nominatim replication --once
-
-If a configuration option is defined through .env file and environment
-variable, then the latter takes precedence.

-### Import and Database Settings
-
-#### NOMINATIM_DATABASE_DSN
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Database connection string |
-| **Format:**        | string: `pgsql:<param1>=<value1>;<param2>=<value2>;...` |
-| **Default:**       | pgsql:dbname=nominatim |
-| **After Changes:** | run `nominatim refresh --website` |
-
-Sets the connection parameters for the Nominatim database. At a minimum
-the name of the database (`dbname`) is required. You can set any additional
-parameter that is understood by libpq. See the [Postgres documentation](https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-PARAMKEYWORDS) for a full list.
-
-!!! note
-    It is usually recommended not to set the password directly in this
-    configuration parameter. Use a
-    [password file](https://www.postgresql.org/docs/current/libpq-pgpass.html)
-    instead.
-
-
-#### NOMINATIM_DATABASE_WEBUSER
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Database query user |
-| **Format:**        | string  |
-| **Default:**       | www-data |
-| **After Changes:** | cannot be changed after import |
-
-Defines the name of the database user that will run search queries. Usually
-this is the user under which the webserver is executed. When running Nominatim
-via php-fpm, you can also define a separate query user. The Postgres user
-needs to be set up before starting the import.
-
-Nominatim grants minimal rights to this user to all tables that are needed
-for running geocoding queries.
-
-
-#### NOMINATIM_DATABASE_MODULE_PATH
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Directory where to find the PostgreSQL server module |
-| **Format:**        | path |
-| **Default:**       | _empty_ (use `<project_directory>/module`) |
-| **After Changes:** | run `nominatim refresh --functions` |
-| **Comment:**       | Legacy tokenizer only |
-
-Defines the directory in which the PostgreSQL server module `nominatim.so`
-is stored. The directory and module must be accessible by the PostgreSQL
-server.
-
-For information on how to use this setting when working with external databases,
-see [Advanced Installations](../admin/Advanced-Installations.md).
-
-The option is only used by the Legacy tokenizer and ignored otherwise.
-
-
-#### NOMINATIM_TOKENIZER
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Tokenizer used for normalizing and parsing queries and names |
-| **Format:**        | string |
-| **Default:**       | legacy |
-| **After Changes:** | cannot be changed after import |
-
-Sets the tokenizer type to use for the import. For more information on
-available tokenizers and how they are configured, see
-[Tokenizers](../customize/Tokenizers.md).
-
-
-#### NOMINATIM_TOKENIZER_CONFIG
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Configuration file for the tokenizer |
-| **Format:**        | path |
-| **Default:**       | _empty_ (default file depends on tokenizer) |
-| **After Changes:** | see documentation for each tokenizer |
-
-Points to the file with additional configuration for the tokenizer.
-See the [Tokenizer](../customize/Tokenizers.md) descriptions for details
-on the file format.
-
-If a relative path is given, then the file is searched first relative to the
-project directory and then in the global settings directory.
-
-#### NOMINATIM_MAX_WORD_FREQUENCY
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Number of occurrences before a word is considered frequent |
-| **Format:**        | int |
-| **Default:**       | 50000 |
-| **After Changes:** | cannot be changed after import |
-| **Comment:**       | Legacy tokenizer only |
-
-The word frequency count is used by the Legacy tokenizer to automatically
-identify _stop words_. Any partial term that occurs more often then what
-is defined in this setting, is effectively ignored during search.
-
-
-#### NOMINATIM_LIMIT_REINDEXING
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Avoid invalidating large areas |
-| **Format:**        | bool |
-| **Default:**       | yes |
-
-Nominatim computes the address of each place at indexing time. This has the
-advantage to make search faster but also means that more objects needs to
-be invalidated when the data changes. For example, changing the name of
-the state of Florida would require recomputing every single address point
-in the state to make the new name searchable in conjunction with addresses.
-
-Setting this option to 'yes' means that Nominatim skips reindexing of contained
-objects when the area becomes too large.
-
-
-#### NOMINATIM_UPDATE_FORWARD_DEPENDENCIES
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Forward geometry changes to dependet objects |
-| **Format:**        | bool |
-| **Default:**       | no |
-| **Comment:**       | EXPERT ONLY. Must not be enabled after import. |
-
-The geometry of OSM ways and relations may change when a node that is part
-of the object is moved around. These changes are not propagated per default.
-The geometry of ways/relations is only updated the next time that the object
-itself is touched. When enabling this option, then dependent objects will
-be marked for update when one of its member objects changes.
-
-Enabling this option may slow down updates significantly.
-
-!!! warning
-    If you want to enable this option, it must be set already on import.
-    Do not enable this option on an existing database that was imported with
-    NOMINATIM_UPDATE_FORWARD_DEPENDENCIES=no.
-    Updates will become unusably slow.
-
-#### NOMINATIM_LANGUAGES
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Restrict search languages |
-| **Format:**        | string: comma-separated list of language codes |
-| **Default:**       | _empty_ |
-
-Normally Nominatim will include all language variants of name:XX
-in the search index. Set this to a comma separated list of language
-codes, to restrict import to a subset of languages.
-
-Currently only affects the initial import of country names and special phrases.
-
-
-#### NOMINATIM_TERM_NORMALIZATION
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Rules for normalizing terms for comparisons |
-| **Format:**        | string: semicolon-separated list of ICU rules |
-| **Default:**       | :: NFD (); [[:Nonspacing Mark:] [:Cf:]] >;  :: lower (); [[:Punctuation:][:Space:]]+ > ' '; :: NFC (); |
-| **Comment:**       | Legacy tokenizer only |
-
-[Special phrases](Special-Phrases.md) have stricter matching requirements than
-normal search terms. They must appear exactly in the query after this term
-normalization has been applied.
-
-Only has an effect on the Legacy tokenizer. For the ICU tokenizer the rules
-defined in the
-[normalization section](Tokenizers.md#normalization-and-transliteration)
-will be used.
-
-
-#### NOMINATIM_USE_US_TIGER_DATA
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Enable searching for Tiger house number data |
-| **Format:**        | boolean |
-| **Default:**       | no |
-| **After Changes:** | run `nominatim refresh --functions` |
-
-When this setting is enabled, search and reverse queries also take data
-from [Tiger house number data](Tiger.md) into account.
-
-
-#### NOMINATIM_USE_AUX_LOCATION_DATA
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Enable searching in external house number tables |
-| **Format:**        | boolean |
-| **Default:**       | no |
-| **After Changes:** | run `nominatim refresh --functions` |
-| **Comment:**       | Do not use. |
-
-When this setting is enabled, search queries also take data from external
-house number tables into account.
-
-*Warning:* This feature is currently unmaintained and should not be used.
-
-
-#### NOMINATIM_HTTP_PROXY
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Use HTTP proxy when downloading data |
-| **Format:**        | boolean |
-| **Default:**       | no |
-
-When this setting is enabled and at least
-[NOMINATIM_HTTP_PROXY_HOST](#nominatim_http_proxy_host) and
-[NOMINATIM_HTTP_PROXY_PORT](#nominatim_http_proxy_port) are set, the
-configured proxy will be used, when downloading external data like
-replication diffs.
-
-
-#### NOMINATIM_HTTP_PROXY_HOST
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Host name of the proxy to use |
-| **Format:**        | string |
-| **Default:**       | _empty_ |
-
-When [NOMINATIM_HTTP_PROXY](#nominatim_http_proxy) is enabled, this setting
-configures the proxy host name.
-
-
-#### NOMINATIM_HTTP_PROXY_PORT
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Port number of the proxy to use |
-| **Format:**        | integer |
-| **Default:**       | 3128 |
-
-When [NOMINATIM_HTTP_PROXY](#nominatim_http_proxy) is enabled, this setting
-configures the port number to use with the proxy.
-
-
-#### NOMINATIM_HTTP_PROXY_LOGIN
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Username for proxies that require login |
-| **Format:**        | string |
-| **Default:**       | _empty_ |
-
-When [NOMINATIM_HTTP_PROXY](#nominatim_http_proxy) is enabled, use this
-setting to define the username for proxies that require a login.
-
-
-#### NOMINATIM_HTTP_PROXY_PASSWORD
-
-| Summary            |                                                     |

-| --------------     | --------------------------------------------------- |
-| **Description:**   | Location of the osm2pgsql binary |
-| **Format:**        | path |
-| **Default:**       | _empty_ (use binary shipped with Nominatim) |
-| **Comment:**       | EXPERT ONLY |
-
-Nominatim uses [osm2pgsql](https://osm2pgsql.org) to load the OSM data
-initially into the database. Nominatim comes bundled with a version of
-osm2pgsql that is guaranteed to be compatible. Use this setting to use
-a different binary instead. You should do this only when you know exactly
-what you are doing. If the osm2pgsql version is not compatible, then the
-result is undefined.
-
-
-#### NOMINATIM_WIKIPEDIA_DATA_PATH
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Directory with the wikipedia importance data |
-| **Format:**        | path |
-| **Default:**       | _empty_ (project directory) |
-
-Set a custom location for the
-[wikipedia ranking file](../admin/Import.md#wikipediawikidata-rankings). When
-unset, Nominatim expects the data to be saved in the project directory.
-
-#### NOMINATIM_ADDRESS_LEVEL_CONFIG
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Configuration file for rank assignments |
-| **Format:**        | path |
-| **Default:**       | address-levels.json |
-
-The _address level configuration_ defines the rank assignments for places. See
-[Place Ranking](Ranking.md) for a detailed explanation what rank assignments
-are and what the configuration file must look like.
-
-When a relative path is given, then the file is searched first relative to the
-project directory and then in the global settings directory.
-
-
-#### NOMINATIM_IMPORT_STYLE
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Configuration to use for the initial OSM data import |
-| **Format:**        | string or path |
-| **Default:**       | extratags |
-
-The _style configuration_ describes which OSM objects and tags are taken
-into consideration for the search database. Nominatim comes with a set
-of pre-configured styles, that may be configured here.
-
-You can also write your own custom style and point the setting to the file
-with the style. When a relative path is given, then the style file is searched
-first relative to the project directory and then in the global settings
-directory.
-
-See [Import Styles](Import-Styles.md)
-for more information on the available internal styles and the format of the
-configuration file.
-
-#### NOMINATIM_FLATNODE_FILE
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Location of osm2pgsql flatnode file |
-| **Format:**        | path |
-| **Default:**       | _empty_ (do not use a flatnote file) |
-| **After Changes:** | Only change when moving the file physically. |
-
-The `osm2pgsql flatnode file` is file that efficiently stores geographic
-location for OSM nodes. For larger imports it can significantly speed up
-the import. When this option is unset, then osm2pgsql uses a PsotgreSQL table
-to store the locations.
-
-When a relative path is given, then the flatnode file is created/searched
-relative to the project directory.
-
-!!! warning
-
-    The flatnode file is not only used during the initial import but also
-    when adding new data with `nominatim add-data` or `nominatim replication`.
-    Make sure you keep the flatnode file around and this setting unmodified,
-    if you plan to add more data or run regular updates.

-
-#### NOMINATIM_TABLESPACE_*
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Group of settings for distributing the database over tablespaces |
-| **Format:**        | string |
-| **Default:**       | _empty_ (do not use a table space) |
-| **After Changes:** | no effect after initial import |
-
-Nominatim allows to distribute the search database over up to 10 different
-[PostgreSQL tablespaces](https://www.postgresql.org/docs/current/manage-ag-tablespaces.html).
-If you use this option, make sure that the tablespaces exist before starting
-the import.
-
-The available tablespace groups are:
-
-NOMINATIM_TABLESPACE_SEARCH_DATA
-:    Data used by the geocoding frontend.
-
-NOMINATIM_TABLESPACE_SEARCH_INDEX
-:    Indexes used by the geocoding frontend.
-
-NOMINATIM_TABLESPACE_OSM_DATA
-:    Raw OSM data cache used for import and updates.
-
-NOMINATIM_TABLESPACE_OSM_DATA
-:    Indexes on the raw OSM data cache.
-
-NOMINATIM_TABLESPACE_PLACE_DATA
-:    Data table with the pre-filtered but still unprocessed OSM data.
-     Used only during imports and updates.
-
-NOMINATIM_TABLESPACE_PLACE_INDEX
-:    Indexes on raw data table. Used only during imports and updates.
-
-NOMINATIM_TABLESPACE_ADDRESS_DATA
-:    Data tables used for computing search terms and addresses of places
-     during import and updates.
-
-NOMINATIM_TABLESPACE_ADDRESS_INDEX

-| **Default:**       | https://planet.openstreetmap.org/replication/minute |
-| **After Changes:** | run `nominatim replication --init` |
-
-Replication services deliver updates to OSM data. Use this setting to choose
-which replication service to use. See [Updates](../admin/Update.md) for more
-information on how to set up regular updates.
-
-#### NOMINATIM_REPLICATION_MAX_DIFF
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Maximum amount of data to download per update cycle (in MB) |
-| **Format:**        | integer |
-| **Default:**       | 50 |
-| **After Changes:** | restart the replication process |
-
-At each update cycle Nominatim downloads diffs until either no more diffs
-are available on the server (i.e. the database is up-to-date) or the limit
-given in this setting is exceeded. Nominatim guarantees to downloads at least
-one diff, if one is available, no matter how small the setting.
-
-The default for this setting is fairly conservative because Nominatim keeps
-all data downloaded in one cycle in RAM. Using large values in a production
-server may interfere badly with the search frontend because it evicts data
-from RAM that is needed for speedy answers to incoming requests. It is usually
-a better idea to keep this setting lower and run multiple update cycles
-to catch up with updates.
-
-When catching up in non-production mode, for example after the initial import,
-the setting can easily be changed temporarily on the command line:
-
-    NOMINATIM_REPLICATION_MAX_DIFF=3000 nominatim replication
-
-
-#### NOMINATIM_REPLICATION_UPDATE_INTERVAL
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Publication interval of the replication service (in seconds) |
-| **Format:**        | integer |
-| **Default:**       | 75 |
-| **After Changes:** | restart the replication process |
-
-This setting determines when Nominatim will attempt to download again a new
-update. The time is computed from the publication date of the last diff
-downloaded. Setting this to a slightly higher value than the actual
-publication interval avoids unnecessary rechecks.
-
-
-#### NOMINATIM_REPLICATION_RECHECK_INTERVAL
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Wait time to recheck for a pending update (in seconds)  |
-| **Format:**        | integer |
-| **Default:**       | 60 |
-| **After Changes:** | restart the replication process |
-
-When replication updates are run in continuous mode (using `nominatim replication`),
-this setting determines how long Nominatim waits until it looks for updates
-again when updates were not available on the server.
-
-Note that this is different from
-[NOMINATIM_REPLICATION_UPDATE_INTERVAL](#nominatim_replication_update_interval).
-Nominatim will never attempt to query for new updates for UPDATE_INTERVAL
-seconds after the current database date. Only after the update interval has
-passed it asks for new data. If then no new data is found, it waits for
-RECHECK_INTERVAL seconds before it attempts again.

-| **Format:**        | url |
-| **Default:**       | _empty_ |
-| **After Changes:** | run `nominatim refresh --website` |
-
-When a mapicon URL is configured, then Nominatim includes an additional `icon`
-field in the responses, pointing to an appropriate icon for the place type.
-
-Map icons used to be included in Nominatim itself but now have moved to the
-[nominatim-ui](https://github.com/osm-search/nominatim-ui/) project. If you
-want the URL to be included in API responses, make the `/mapicon`

-| --------------     | --------------------------------------------------- |
-| **Description:**   | Language of responses when no language is requested |
-| **Format:**        | language code |
-| **Default:**       | _empty_ (use the local language of the feature) |
-| **After Changes:** | run `nominatim refresh --website` |
-
-Nominatim localizes the place names in responses when the corresponding
-translation is available. Users can request a custom language setting through
-the HTTP accept-languages header or through the explicit parameter
-[accept-languages](../api/Search.md#language-of-results). If neither is
-given, it falls back to this setting. If the setting is also empty, then
-the local languages (in OSM: the name tag without any language suffix) is
-used.

-| **Format:**        | boolean |
-| **Default:**       | no |
-| **After Changes:** | run `nominatim refresh --website` |
-
-This feature is currently undocumented and potentially broken.
-

-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Threshold for switching the search index lookup strategy |
-| **Format:**        | integer |
-| **Default:**       | 500 |
-| **After Changes:** | run `nominatim refresh --website` |
-
-This setting defines the threshold over which a name is no longer considered
-as rare. When searching for places with rare names, only the name is used
-for place lookups. Otherwise the name and any address information is used.
-
-This setting only has an effect after `nominatim refresh --word-counts` has
-been called to compute the word frequencies.
-
-
-#### NOMINATIM_LOOKUP_MAX_COUNT
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |

-| **Format:**        | integer |
-| **Default:**       | 50 |
-| **After Changes:** | run `nominatim refresh --website` |
-
-The /lookup point accepts list of ids to look up address details for. This
-setting restricts the number of places a user may look up with a single
-request.
-

-| **Description:**   | Number of different geometry formats that may be returned |
-| **Format:**        | integer |
-| **Default:**       | 1 |
-| **After Changes:** | run `nominatim refresh --website` |
-
-Nominatim supports returning full geometries of places. The geometries may
-be requested in different formats with one of the
-[`polygon_*` parameters](../api/Search.md#polygon-output). Use this
-setting to restrict the number of geometry types that may be requested
-with a single query.
-
-Setting this parameter to 0 disables polygon output completely.

-| **After Changes:** | run `nominatim refresh --website` |
-
-Enable logging of requests into a file with this setting by setting the log
-file where to log to. A relative file name is assumed to be relative to
-the project directory.
-
-
-The entries in the log file have the following format:
-
-    <request time> <execution time in s> <number of results> <type> "<query string>"
-
-Request time is the time when the request was started. The execution time is
-given in seconds and corresponds to the time the query took executing in PHP.
-type contains the name of the endpoint used.

-As described in the [Import section](../admin/Import.md), it is possible to
-import special phrases from the wiki with the following command:
-
-```sh
-nominatim special-phrases --import-from-wiki
-```
-
-## Importing custom special phrases

-But, it is also possible to import some phrases from a csv file. 
-To do so, you have access to the following command:
-
-```sh
-nominatim special-phrases --import-from-csv <csv file>
-```
-
-Note that the two previous import commands will update the phrases from your database.
-This means that if you import some phrases from a csv file, only the phrases
-present in the csv file will be kept into the database. All other phrases will
-be removed.
-
-If you want to only add new phrases and not update the other ones you can add
-the argument `--no-replace` to the import command. For example:
-
-```sh
-nominatim special-phrases --import-from-csv <csv file> --no-replace
-```
-
-This will add the phrases present in the csv file into the database without

-# Tokenizers
-
-The tokenizer module in Nominatim is responsible for analysing the names given
-to OSM objects and the terms of an incoming query in order to make sure, they
-can be matched appropriately.
-
-Nominatim offers different tokenizer modules, which behave differently and have
-different configuration options. This sections describes the tokenizers and how
-they can be configured.
-
-!!! important
-    The use of a tokenizer is tied to a database installation. You need to choose
-    and configure the tokenizer before starting the initial import. Once the import
-    is done, you cannot switch to another tokenizer anymore. Reconfiguring the
-    chosen tokenizer is very limited as well. See the comments in each tokenizer
-    section.
-
-## Legacy tokenizer
-
-The legacy tokenizer implements the analysis algorithms of older Nominatim
-versions. It uses a special Postgresql module to normalize names and queries.
-This tokenizer is automatically installed and used when upgrading an older
-database. It should not be used for new installations anymore.
-
-### Compiling the PostgreSQL module
-
-The tokeinzer needs a special C module for PostgreSQL which is not compiled
-by default. If you need the legacy tokenizer, compile Nominatim as follows:
-
-```
-mkdir build
-cd build
-cmake -DBUILD_MODULE=on
-make
-```
-
-### Enabling the tokenizer
-
-To enable the tokenizer add the following line to your project configuration:
-
-```
-NOMINATIM_TOKENIZER=legacy
-```
-
-The Postgresql module for the tokenizer is available in the `module` directory
-and also installed with the remainder of the software under
-`lib/nominatim/module/nominatim.so`. You can specify a custom location for
-the module with
-
-```
-NOMINATIM_DATABASE_MODULE_PATH=<path to directory where nominatim.so resides>
-```
-
-This is in particular useful when the database runs on a different server.
-See [Advanced installations](../admin/Advanced-Installations.md#importing-nominatim-to-an-external-postgresql-database) for details.
-
-There are no other configuration options for the legacy tokenizer. All
-normalization functions are hard-coded.
-
-## ICU tokenizer
-
-The ICU tokenizer uses the [ICU library](http://site.icu-project.org/) to
-normalize names and queries. It also offers configurable decomposition and
-abbreviation handling.
-This tokenizer is currently the default.
-
-To enable the tokenizer add the following line to your project configuration:
-
-```
-NOMINATIM_TOKENIZER=icu
-```
-
-### How it works
-
-On import the tokenizer processes names in the following three stages:
-
-1. During the **Sanitizer step** incoming names are cleaned up and converted to
-   **full names**. This step can be used to regularize spelling, split multi-name
-   tags into their parts and tag names with additional attributes. See the
-   [Sanitizers section](#sanitizers) below for available cleaning routines.
-2. The **Normalization** part removes all information from the full names
-   that are not relevant for search.
-3. The **Token analysis** step takes the normalized full names and creates
-   all transliterated variants under which the name should be searchable.
-   See the [Token analysis](#token-analysis) section below for more
-   information.
-
-During query time, only normalization and transliteration are relevant.
-An incoming query is first split into name chunks (this usually means splitting
-the string at the commas) and the each part is normalised and transliterated.
-The result is used to look up places in the search index.
-
-### Configuration
-
-The ICU tokenizer is configured using a YAML file which can be configured using
-`NOMINATIM_TOKENIZER_CONFIG`. The configuration is read on import and then
-saved as part of the internal database status. Later changes to the variable
-have no effect.
-
-Here is an example configuration file:
-
-``` yaml
-normalization:
-    - ":: lower ()"
-    - "ß > 'ss'" # German szet is unimbigiously equal to double ss
-transliteration:
-    - !include /etc/nominatim/icu-rules/extended-unicode-to-asccii.yaml
-    - ":: Ascii ()"
-sanitizers:
-    - step: split-name-list
-token-analysis:
-    - analyzer: generic
-      variants:
-          - !include icu-rules/variants-ca.yaml
-          - words:
-              - road -> rd
-              - bridge -> bdge,br,brdg,bri,brg
-      mutations:
-          - pattern: 'ä'
-            replacements: ['ä', 'ae']
-```
-
-The configuration file contains four sections:
-`normalization`, `transliteration`, `sanitizers` and `token-analysis`.
-
-#### Normalization and Transliteration
-
-The normalization and transliteration sections each define a set of
-ICU rules that are applied to the names.
-
-The **normalisation** rules are applied after sanitation. They should remove
-any information that is not relevant for search at all. Usual rules to be
-applied here are: lower-casing, removing of special characters, cleanup of
-spaces.
-
-The **transliteration** rules are applied at the end of the tokenization
-process to transfer the name into an ASCII representation. Transliteration can
-be useful to allow for further fuzzy matching, especially between different
-scripts.
-
-Each section must contain a list of
-[ICU transformation rules](https://unicode-org.github.io/icu/userguide/transforms/general/rules.html).
-The rules are applied in the order in which they appear in the file.
-You can also include additional rules from external yaml file using the
-`!include` tag. The included file must contain a valid YAML list of ICU rules
-and may again include other files.
-
-!!! warning
-    The ICU rule syntax contains special characters that conflict with the
-    YAML syntax. You should therefore always enclose the ICU rules in
-    double-quotes.
-
-#### Sanitizers
-
-The sanitizers section defines an ordered list of functions that are applied
-to the name and address tags before they are further processed by the tokenizer.
-They allows to clean up the tagging and bring it to a standardized form more
-suitable for building the search index.
-
-!!! hint
-    Sanitizers only have an effect on how the search index is built. They
-    do not change the information about each place that is saved in the
-    database. In particular, they have no influence on how the results are
-    displayed. The returned results always show the original information as
-    stored in the OpenStreetMap database.
-
-Each entry contains information of a sanitizer to be applied. It has a
-mandatory parameter `step` which gives the name of the sanitizer. Depending
-on the type, it may have additional parameters to configure its operation.
-
-The order of the list matters. The sanitizers are applied exactly in the order
-that is configured. Each sanitizer works on the results of the previous one.
-
-The following is a list of sanitizers that are shipped with Nominatim.

-
-#### Token Analysis
-
-Token analyzers take a full name and transform it into one or more normalized
-form that are then saved in the search index. In its simplest form, the
-analyzer only applies the transliteration rules. More complex analyzers
-create additional spelling variants of a name. This is useful to handle
-decomposition and abbreviation.
-
-The ICU tokenizer may use different analyzers for different names. To select
-the analyzer to be used, the name must be tagged with the `analyzer` attribute
-by a sanitizer (see for example the
-[tag-analyzer-by-language sanitizer](#tag-analyzer-by-language)).
-
-The token-analysis section contains the list of configured analyzers. Each
-analyzer must have an `id` parameter that uniquely identifies the analyzer.
-The only exception is the default analyzer that is used when no special
-analyzer was selected. There are analysers with special ids:
-
- * '@housenumber'. If an analyzer with that name is present, it is used
-   for normalization of house numbers.
- * '@potcode'. If an analyzer with that name is present, it is used
-   for normalization of postcodes.
-
-Different analyzer implementations may exist. To select the implementation,
-the `analyzer` parameter must be set. The different implementations are
-described in the following.
-
-##### Generic token analyzer
-
-The generic analyzer `generic` is able to create variants from a list of given
-abbreviation and decomposition replacements and introduce spelling variations.
-
-###### Variants
-
-The optional 'variants' section defines lists of replacements which create alternative
-spellings of a name. To create the variants, a name is scanned from left to
-right and the longest matching replacement is applied until the end of the
-string is reached.
-
-The variants section must contain a list of replacement groups. Each group
-defines a set of properties that describes where the replacements are
-applicable. In addition, the word section defines the list of replacements
-to be made. The basic replacement description is of the form:
-
-```
-<source>[,<source>[...]] => <target>[,<target>[...]]
-```
-
-The left side contains one or more `source` terms to be replaced. The right side
-lists one or more replacements. Each source is replaced with each replacement
-term.
-
-!!! tip
-    The source and target terms are internally normalized using the
-    normalization rules given in the configuration. This ensures that the
-    strings match as expected. In fact, it is better to use unnormalized
-    words in the configuration because then it is possible to change the
-    rules for normalization later without having to adapt the variant rules.
-
-###### Decomposition
-
-In its standard form, only full words match against the source. There
-is a special notation to match the prefix and suffix of a word:
-
-``` yaml
-- ~strasse => str  # matches "strasse" as full word and in suffix position
-- hinter~ => hntr  # matches "hinter" as full word and in prefix position
-```
-
-There is no facility to match a string in the middle of the word. The suffix
-and prefix notation automatically trigger the decomposition mode: two variants
-are created for each replacement, one with the replacement attached to the word
-and one separate. So in above example, the tokenization of "hauptstrasse" will
-create the variants "hauptstr" and "haupt str". Similarly, the name "rote strasse"
-triggers the variants "rote str" and "rotestr". By having decomposition work
-both ways, it is sufficient to create the variants at index time. The variant
-rules are not applied at query time.
-
-To avoid automatic decomposition, use the '|' notation:
-
-``` yaml
-- ~strasse |=> str
-```
-
-simply changes "hauptstrasse" to "hauptstr" and "rote strasse" to "rote str".
-
-###### Initial and final terms
-
-It is also possible to restrict replacements to the beginning and end of a
-name:
-
-``` yaml
-- ^south => s  # matches only at the beginning of the name
-- road$ => rd  # matches only at the end of the name
-```
-
-So the first example would trigger a replacement for "south 45th street" but
-not for "the south beach restaurant".
-
-###### Replacements vs. variants
-
-The replacement syntax `source => target` works as a pure replacement. It changes
-the name instead of creating a variant. To create an additional version, you'd
-have to write `source => source,target`. As this is a frequent case, there is
-a shortcut notation for it:
-
-```
-<source>[,<source>[...]] -> <target>[,<target>[...]]
-```
-
-The simple arrow causes an additional variant to be added. Note that
-decomposition has an effect here on the source as well. So a rule
-
-``` yaml
-- "~strasse -> str"
-```
-
-means that for a word like `hauptstrasse` four variants are created:
-`hauptstrasse`, `haupt strasse`, `hauptstr` and `haupt str`.
-
-###### Mutations
-
-The 'mutation' section in the configuration describes an additional set of
-replacements to be applied after the variants have been computed.
-
-Each mutation is described by two parameters: `pattern` and `replacements`.
-The pattern must contain a single regular expression to search for in the
-variant name. The regular expressions need to follow the syntax for
-[Python regular expressions](file:///usr/share/doc/python3-doc/html/library/re.html#regular-expression-syntax).
-Capturing groups are not permitted.
-`replacements` must contain a list of strings that the pattern
-should be replaced with. Each occurrence of the pattern is replaced with
-all given replacements. Be mindful of combinatorial explosion of variants.
-
-###### Modes
-
-The generic analyser supports a special mode `variant-only`. When configured
-then it consumes the input token and emits only variants (if any exist). Enable
-the mode by adding:
-
-```
-  mode: variant-only
-```
-
-to the analyser configuration.
-
-##### Housenumber token analyzer
-
-The analyzer `housenumbers` is purpose-made to analyze house numbers. It
-creates variants with optional spaces between numbers and letters. Thus,
-house numbers of the form '3 a', '3A', '3-A' etc. are all considered equivalent.
-
-The analyzer cannot be customized.
-
-##### Postcode token analyzer
-
-The analyzer `postcodes` is pupose-made to analyze postcodes. It supports
-a 'lookup' varaint of the token, which produces variants with optional
-spaces. Use together with the clean-postcodes sanitizer.
-
-The analyzer cannot be customized.
-
-### Reconfiguration
-
-Changing the configuration after the import is currently not possible, although
-this feature may be added at a later time.

-# Database Layout
-
-### Import tables
-
-OSM data is initially imported using [osm2pgsql](https://osm2pgsql.org).
-Nominatim uses its own data output style 'gazetteer', which differs from the
-output style created for map rendering.
-
-The import process creates the following tables:
-
-![osm2pgsql tables](osm2pgsql-tables.svg)
-
-The `planet_osm_*` tables are the usual backing tables for OSM data. Note
-that Nominatim uses them to look up special relations and to find nodes on
-ways.
-
-The gazetteer style produces a single table `place` as output with the following
-columns:
-
- * `osm_type` - kind of OSM object (**N** - node, **W** - way, **R** - relation)
- * `osm_id` - original OSM ID
- * `class` - key of principal tag defining the object type
- * `type` - value of principal tag defining the object type
- * `name` - collection of tags that contain a name or reference
- * `admin_level` - numerical value of the tagged administrative level
- * `address` - collection of tags defining the address of an object
- * `extratags` - collection of additional interesting tags that are not
-                 directly relevant for searching
- * `geometry` - geometry of the object (in WGS84)
-
-A single OSM object may appear multiple times in this table when it is tagged
-with multiple tags that may constitute a principal tag. Take for example a
-motorway bridge. In OSM, this would be a way which is tagged with
-`highway=motorway` and `bridge=yes`. This way would appear in the `place` table
-once with `class` of `highway` and once with a `class` of `bridge`. Thus the
-*unique key* for `place` is (`osm_type`, `osm_id`, `class`).
-
-How raw OSM tags are mapped to the columns in the place table is to a certain
-degree configurable. See [Customizing Import Styles](../customize/Import-Styles.md)
-for more information.
-
-### Search tables
-
-The following tables carry all information needed to do the search:
-
-![search tables](search-tables.svg)
-
-The **placex** table is the central table that saves all information about the
-searchable places in Nominatim. The basic columns are the same as for the
-place table and have the same meaning. The placex tables adds the following
-additional columns:
-
- * `place_id` - the internal unique ID to identify the place
- * `partition` - the id to use with partitioned tables (see below)
- * `geometry_sector` - a location hash used for geographically close ordering
- * `parent_place_id` - the next higher place in the address hierarchy, only
-   relevant for POI-type places (with rank 30)
- * `linked_place_id` - place ID of the place this object has been merged with.
-   When this ID is set, then the place is invisible for search.
- * `importance` - measure how well known the place is
- * `rank_search`, `rank_address` - search and address rank (see [Customizing ranking](../customize/Ranking.md)
- * `wikipedia` - the wikipedia page used for computing the importance of the place
- * `country_code` - the country the place is located in
- * `housenumber` - normalized housenumber, if the place has one
- * `postcode` - computed postcode for the place
- * `indexed_status` - processing status of the place (0 - ready, 1 - freshly inserted, 2 - needs updating, 100 - needs deletion)
- * `indexed_date` - timestamp when the place was processed last
- * `centroid` - a point feature for the place
-
-The **location_property_osmline** table is a special table for
-[address interpolations](https://wiki.openstreetmap.org/wiki/Addresses#Using_interpolation).
-The columns have the same meaning and use as the columns with the same name in
-the placex table. Only three columns are special:
-
- * `startnumber` and `endnumber` - beginning and end of the number range
-    for the interpolation
- * `interpolationtype` - a string `odd`, `even` or `all` to indicate
-    the interval between the numbers
-
-Address interpolations are always ways in OSM, which is why there is no column
-`osm_type`.
-
-The **location_postcode** table holds computed centroids of all postcodes that
-can be found in the OSM data. The meaning of the columns is again the same
-as that of the placex table.
-
-Every place needs an address, a set of surrounding places that describe the
-location of the place. The set of address places is made up of OSM places
-themselves. The **place_addressline** table cross-references for each place
-all the places that make up its address. Two columns define the address
-relation:
-
-  * `place_id` - reference to the place being addressed
-  * `address_place_id` - reference to the place serving as an address part
-
-The most of the columns cache information from the placex entry of the address
-part. The exceptions are:
-
-  * `fromarea` - is true if the address part has an area geometry and can
-    therefore be considered preceise
-  * `isaddress` - is true if the address part should show up in the address
-    output. Sometimes there are multiple places competing for for same address
-    type (e.g. multiple cities) and this field resolves the tie.
-
-The **search_name** table contains the search index proper. It saves for each
-place the terms with which the place can be found. The terms are split into
-the name itself and all terms that make up the address. The table mirrors some
-of the columns from placex for faster lookup.
-
-Search terms are not saved as strings. Each term is assigned an integer and those
-integers are saved in the name and address vectors of the search_name table. The
-**word** table serves as the lookup table from string to such a word ID. The
-exact content of the word table depends on the [tokenizer](Tokenizers.md) used.
-
-## Address computation tables
-
-Next to the main search tables, there is a set of secondary helper tables used
-to compute the address relations between places. These tables are partitioned.
-Each country is assigned a partition number in the country_name table (see
-below) and the data is then split between a set of tables, one for each
-partition. Note that Nominatim still manually manages partitioned tables.
-Native support for partitions in PostgreSQL only became usable with version 13.
-It will be a little while before Nominatim drops support for older versions.
-
-![address tables](address-tables.svg)
-
-The **search_name_X** tables are used to look up streets that appear in the
-`addr:street` tag.
-
-The **location_area_large_X** tables are used to look up larger areas
-(administrative boundaries and place nodes) either through their geographic
-closeness or through `addr:*` entries.
-
-The **location_road_X** tables are used to find the closest street for a
-dependent place.
-
-All three table cache specific information from the placex table for their
-selected subset of places:
-
- * `keywords` and `name_vector` contain lists of term ids (from the word table)
-   that the full name of the place should match against
- * `isguess` is true for places that are not described by an area
-
-All other columns reflect their counterpart in the placex table.
-
-## Static data tables
-
-Nominatim also creates a number of static tables at import:
-
- * `nominatim_properties` saves settings that must not be changed after
-    import
- * `address_levels` save the rank information from the
-   [ranking configuration](../customize/Ranking.md)
- * `country_name` contains a fallback of names for all countries, their
-   default languages and saves the assignment of countries to partitions.
- * `country_osm_grid` provides a fallback for country geometries
-
-## Auxiliary data tables
-
-Finally there are some table for auxiliary data:
-
- * `location_property_tiger` - saves housenumber from the Tiger import. Its
-   layout is similar to that of `location_propoerty_osmline`.
- * `place_class_*` tables are helper tables to facilitate lookup of POIs
-   by their class and type. They exist because it is not possible to create
-   combined indexes with geometries.

-# Setting up Nominatim for Development
-
-This chapter gives an overview how to set up Nominatim for development
-and how to run tests.
-
-!!! Important
-    This guide assumes that you develop under the latest version of Ubuntu. You
-    can of course also use your favourite distribution. You just might have to
-    adapt the commands below slightly, in particular the commands for installing
-    additional software.
-
-## Installing Nominatim
-
-The first step is to install Nominatim itself. Please follow the installation
-instructions in the [Admin section](../admin/Installation.md). You don't need
-to set up a webserver for development, the webserver that is included with PHP
-is sufficient.
-
-If you want to run Nominatim in a VM via Vagrant, use the default `ubuntu` setup.
-Vagrant's libvirt provider runs out-of-the-box under Ubuntu. You also need to
-install an NFS daemon to enable directory sharing between host and guest. The
-following packages should get you started:
-
-    sudo apt install vagrant vagrant-libvirt libvirt-daemon nfs-kernel-server
-
-## Prerequisites for testing and documentation
-
-The Nominatim test suite consists of behavioural tests (using behave) and
-unit tests (using PHPUnit for PHP code and pytest for Python code).
-It has the following additional requirements:
-
-* [behave test framework](https://behave.readthedocs.io) >= 1.2.6
-* [phpunit](https://phpunit.de) (9.5 is known to work)
-* [PHP CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer)
-* [Pylint](https://pylint.org/) (CI always runs the latest version from pip)
-* [mypy](http://mypy-lang.org/) (plus typing information for external libs)
-* [Python Typing Extensions](https://github.com/python/typing_extensions) (for Python < 3.9)
-* [pytest](https://pytest.org)
-
-The documentation is built with mkdocs:
-
-* [mkdocs](https://www.mkdocs.org/) >= 1.1.2
-* [mkdocstrings](https://mkdocstrings.github.io/) >= 0.16
-* [mkdocstrings-python-legacy](https://mkdocstrings.github.io/python-legacy/)
-
-### Installing prerequisites on Ubuntu/Debian
-
-Some of the Python packages require the newest version which is not yet
-available with the current distributions. Therefore it is recommended to
-install pip to get the newest versions.
-
-To install all necessary packages run:
-
-```sh
-sudo apt install php-cgi phpunit php-codesniffer \
-                 python3-pip python3-setuptools python3-dev
-
-pip3 install --user behave mkdocs mkdocstrings pytest pylint \
-                    mypy types-PyYAML types-jinja2 types-psycopg2 types-psutil
-```
-
-The `mkdocs` executable will be located in `.local/bin`. You may have to add
-this directory to your path, for example by running:
-
-```
-echo 'export PATH=~/.local/bin:$PATH' > ~/.profile
-```
-
-If your distribution does not have PHPUnit 7.3+, you can install it (as well
-as CodeSniffer) via composer:
-
-```
-sudo apt-get install composer
-composer global require "squizlabs/php_codesniffer=*"
-composer global require "phpunit/phpunit=8.*"
-```
-
-The binaries are found in `.config/composer/vendor/bin`. You need to add this
-to your PATH as well:
-
-```
-echo 'export PATH=~/.config/composer/vendor/bin:$PATH' > ~/.profile
-```
-
-
-## Executing Tests
-
-All tests are located in the `/test` directory.
-
-To run all tests just go to the build directory and run make:
-
-```sh
-cd build
-make test
-```
-
-For more information about the structure of the tests and how to change and
-extend the test suite, see the [Testing chapter](Testing.md).
-
-## Documentation Pages
-
-The [Nominatim documentation](https://nominatim.org/release-docs/develop/) is
-built using the [MkDocs](https://www.mkdocs.org/) static site generation
-framework. The master branch is automatically deployed every night on
-[https://nominatim.org/release-docs/develop/](https://nominatim.org/release-docs/develop/)
-
-To build the documentation, go to the build directory and run
-
-```
-make doc
-INFO - Cleaning site directory
-INFO - Building documentation to directory: /home/vagrant/build/site-html
-```
-
-This runs `mkdocs build` plus extra transformation of some files and adds
-symlinks (see `CMakeLists.txt` for the exact steps).
-
-Now you can start webserver for local testing
-
-```
-build> make serve-doc
-[server:296] Serving on http://127.0.0.1:8000
-[handlers:62] Start watching changes
-```
-
-If you develop inside a Vagrant virtual machine, use a port that is forwarded
-to your host:
-
-```
-build> PYTHONPATH=$SRCDIR mkdocs serve --dev-addr 0.0.0.0:8088
-[server:296] Serving on http://0.0.0.0:8088
-[handlers:62] Start watching changes
-```

-# Writing custom sanitizer and token analysis modules for the ICU tokenizer
-
-The [ICU tokenizer](../customize/Tokenizers.md#icu-tokenizer) provides a
-highly customizable method to pre-process and normalize the name information
-of the input data before it is added to the search index. It comes with a
-selection of sanitizers and token analyzers which you can use to adapt your
-installation to your needs. If the provided modules are not enough, you can
-also provide your own implementations. This section describes the API
-of sanitizers and token analysis.
-
-!!! warning
-    This API is currently in early alpha status. While this API is meant to
-    be a public API on which other sanitizers and token analyzers may be
-    implemented, it is not guaranteed to be stable at the moment.
-
-
-## Using non-standard sanitizers and token analyzers
-
-Sanitizer names (in the `step` property) and token analysis names (in the
-`analyzer`) may refer to externally supplied modules. There are two ways
-to include external modules: through a library or from the project directory.
-
-To include a module from a library, use the absolute import path as name and
-make sure the library can be found in your PYTHONPATH.
-
-To use a custom module without creating a library, you can put the module
-somewhere in your project directory and then use the relative path to the
-file. Include the whole name of the file including the `.py` ending.
-
-## Custom sanitizer modules
-
-A sanitizer module must export a single factory function `create` with the
-following signature:
-
-``` python
-def create(config: SanitizerConfig) -> Callable[[ProcessInfo], None]
-```
-
-The function receives the custom configuration for the sanitizer and must
-return a callable (function or class) that transforms the name and address
-terms of a place. When a place is processed, then a `ProcessInfo` object
-is created from the information that was queried from the database. This
-object is sequentially handed to each configured sanitizer, so that each
-sanitizer receives the result of processing from the previous sanitizer.
-After the last sanitizer is finished, the resulting name and address lists
-are forwarded to the token analysis module.
-
-Sanitizer functions are instantiated once and then called for each place
-that is imported or updated. They don't need to be thread-safe.
-If multi-threading is used, each thread creates their own instance of
-the function.
-
-### Sanitizer configuration
-
-::: nominatim.tokenizer.sanitizers.config.SanitizerConfig
-    rendering:
-        show_source: no
-        heading_level: 6
-
-### The main filter function of the sanitizer
-
-The filter function receives a single object of type `ProcessInfo`
-which has with three members:
-
- * `place`: read-only information about the place being processed.
-   See PlaceInfo below.
- * `names`: The current list of names for the place. Each name is a
-   PlaceName object.
- * `address`: The current list of address names for the place. Each name
-   is a PlaceName object.
-
-While the `place` member is provided for information only, the `names` and
-`address` lists are meant to be manipulated by the sanitizer. It may add and
-remove entries, change information within a single entry (for example by
-adding extra attributes) or completely replace the list with a different one.
-
-#### PlaceInfo - information about the place
-
-::: nominatim.data.place_info.PlaceInfo
-    rendering:
-        show_source: no
-        heading_level: 6
-
-
-#### PlaceName - extended naming information
-
-::: nominatim.data.place_name.PlaceName
-    rendering:
-        show_source: no
-        heading_level: 6
-
-
-### Example: Filter for US street prefixes
-
-The following sanitizer removes the directional prefixes from street names
-in the US:
-
-``` python
-import re
-
-def _filter_function(obj):
-    if obj.place.country_code == 'us' \
-       and obj.place.rank_address >= 26 and obj.place.rank_address <= 27:
-        for name in obj.names:
-            name.name = re.sub(r'^(north|south|west|east) ',
-                               '',
-                               name.name,
-                               flags=re.IGNORECASE)
-
-def create(config):
-    return _filter_function
-```
-
-This is the most simple form of a sanitizer module. If defines a single
-filter function and implements the required `create()` function by returning
-the filter.
-
-The filter function first checks if the object is interesting for the
-sanitizer. Namely it checks if the place is in the US (through `country_code`)
-and it the place is a street (a `rank_address` of 26 or 27). If the
-conditions are met, then it goes through all available names and
-removes any leading directional prefix using a simple regular expression.
-
-Save the source code in a file in your project directory, for example as
-`us_streets.py`. Then you can use the sanitizer in your `icu_tokenizer.yaml`:
-
-``` yaml
-...
-sanitizers:
-    - step: us_streets.py
-...
-```
-
-!!! warning
-    This example is just a simplified show case on how to create a sanitizer.
-    It is not really read for real-world use: while the sanitizer would
-    correcly transform `West 5th Street` into `5th Street`. it would also
-    shorten a simple `North Street` to `Street`.
-
-For more sanitizer examples, have a look at the sanitizers provided by Nominatim.
-They can be found in the directory
-[`nominatim/tokenizer/sanitizers`](https://github.com/osm-search/Nominatim/tree/master/nominatim/tokenizer/sanitizers).

-### Example: Creating acronym variants for long names
-
-The following example of a token analysis module creates acronyms from
-very long names and adds them as a variant:
-
-``` python
-class AcronymMaker:
-    """ This class is the actual analyzer.
-    """
-    def __init__(self, norm, trans):
-        self.norm = norm
-        self.trans = trans
-
-
-    def get_canonical_id(self, name):
-        # In simple cases, the normalized name can be used as a canonical id.
-        return self.norm.transliterate(name.name).strip()
-
-
-    def compute_variants(self, name):
-        # The transliterated form of the name always makes up a variant.
-        variants = [self.trans.transliterate(name)]
-
-        # Only create acronyms from very long words.
-        if len(name) > 20:
-            # Take the first letter from each word to form the acronym.
-            acronym = ''.join(w[0] for w in name.split())
-            # If that leds to an acronym with at least three letters,
-            # add the resulting acronym as a variant.
-            if len(acronym) > 2:
-                # Never forget to transliterate the variants before returning them.
-                variants.append(self.trans.transliterate(acronym))
-
-        return variants
-
-# The following two functions are the module interface.
-
-def configure(rules, normalizer, transliterator):
-    # There is no configuration to parse and no data to set up.
-    # Just return an empty configuration.
-    return None
-
-
-def create(normalizer, transliterator, config):
-    # Return a new instance of our token analysis class above.
-    return AcronymMaker(normalizer, transliterator)
-```
-
-Given the name `Trans-Siberian Railway`, the code above would return the full
-name `Trans-Siberian Railway` and the acronym `TSR` as variant, so that
-searching would work for both.
-
-## Sanitizers vs. Token analysis - what to use for variants?
-
-It is not always clear when to implement variations in the sanitizer and
-when to write a token analysis module. Just take the acronym example
-above: it would also have been possible to write a sanitizer which adds the
-acronym as an additional name to the name list. The result would have been
-similar. So which should be used when?
-
-The most important thing to keep in mind is that variants created by the
-token analysis are only saved in the word lookup table. They do not need
-extra space in the search index. If there are many spelling variations, this
-can mean quite a significant amount of space is saved.
-
-When creating additional names with a sanitizer, these names are completely
-independent. In particular, they can be fed into different token analysis
-modules. This gives a much greater flexibility but at the price that the
-additional names increase the size of the search index.

-# Indexing Places
-
-In Nominatim, the word __indexing__ refers to the process that takes the raw
-OpenStreetMap data from the place table, enriches it with address information
-and creates the search indexes. This section explains the basic data flow.
-
-
-## Initial import
-
-After osm2pgsql has loaded the raw OSM data into the place table,
-the data is copied to the final search tables placex and location_property_osmline.
-While they are copied, some basic properties are added:
-
- * country_code, geometry_sector and partition
- * initial search and address rank
-
-In addition the column `indexed_status` is set to `1` marking the place as one
-that needs to be indexed.
-
-All this happens in the triggers `placex_insert` and `osmline_insert`.
-
-## Indexing
-
-The main work horse of the data import is the indexing step, where Nominatim
-takes every place from the placex and location_property_osmline tables where
-the indexed_status != 0 and computes the search terms and the address parts
-of the place.
-
-The indexing happens in three major steps:
-
-1. **Data preparation** - The indexer gets the data for the place to be indexed
-   from the database.
-
-2. **Search name processing** - The prepared data is given to the
-   tokenizer which computes the search terms from the names
-   and potentially other information.
-
-3. **Address processing** - The indexer then hands the prepared data and the
-   tokenizer information back to the database via an `INSERT` statement which
-   also sets the indexed_status to `0`. This triggers the update triggers
-   `placex_update`/`osmline_update` which do the work of computing address
-   parts and filling all the search tables.
-
-When computing the address terms of a place, Nominatim relies on the processed
-search names of all the address parts. That is why places are processed in rank
-order, from smallest rank to largest. To ensure correct handling of linked
-place nodes, administrative boundaries are processed before all other places.
-
-Apart from these restrictions, each place can be indexed independently
-from the others. This allows a large degree of parallelization during the indexing.
-It also means that the indexing process can be interrupted at any time and
-will simply pick up where it left of when restarted.
-
-### Data preparation
-
-The data preparation step computes and retrieves all data for a place that
-might be needed for the next step of processing the search name. That includes
-
-* location information (country code)
-* place classification (class, type, ranks)
-* names (including names of linked places)
-* address information (`addr:*` tags)
-
-Data preparation is implemented in pl/PgSQL mostly in the functions
-`placex_indexing_prepare()` and `get_interpolation_address()`.
-
-#### `addr:*` tag inheritance
-
-Nominatim has limited support for inheriting address tags from a building
-to POIs inside the building. This only works when the address tags are on the
-building outline. Any rank 30 object inside such a building or on its outline
-inherits all address tags when it does not have any address tags of its own.
-
-The inheritance is computed in the data preparation step.
-
-### Search name processing
-
-The prepared place information is handed to the tokenizer next. This is a
-Python module responsible for processing the names  from both name and address
-terms and building up the word index from them. The process is explained in
-more detail in the [Tokenizer chapter](Tokenizers.md).
-
-### Address processing
-
-Finally, the preprocessed place information and the results of the search name
-processing are written back to the database. At this point the update trigger
-of the placex/location_property_osmline tables take over and fill all the
-dependent tables. This makes up the most work-intensive part of the indexing.
-
-Nominatim distinguishes between dependent and independent places.
-**Dependent places** are all places on rank 30: house numbers, POIs etc. These
-places don't have a full address of their own. Instead they are attached to
-a parent street or place and use the information of the parent for searching
-and displaying information. Everything else are **independent places**: streets,
-parks, water bodies, suburbs, cities, states etc.  They receive a full address
-on their own.
-
-The address processing for both types of places is very different.
-
-#### Independent places
-
-To compute the address of an independent place Nominatim searches for all
-places that cover the place to compute the address for at least partially.
-For places with an area, that area is used to check for coverage. For place
-nodes an artificial square area is computed according to the rank of
-the place. The lower the rank the lager the area. The `location_area_large_X`
-tables are there to facilitate the lookup. All places that can function as
-the address of another place are saved in those tables.
-
-`addr:*` and `isin:*` tags are taken into account to compute the address, too.
-Nominatim will give preference to places with the same name as in these tags
-when looking for places in the vicinity. If there are no matching place names
-at all, then the tags are at least added to the search index. That means that
-the names will not be shown in the result as the 'address' of the place, but
-searching by them still works.
-
-Independent places are always added to the global search index `search_name`.
-
-#### Dependent places
-
-Dependent places skip the full address computation for performance reasons.
-Instead they just find a parent place to attach themselves to.
-
-![parenting of dependent places](parenting-flow.svg)
-
-By default a POI
-or house number will be attached to the closest street. That can be any major
-or minor street indexed by Nominatim. In the default configuration that means
-that it can attach itself to a footway but only when it has a name.
-
-When the dependent place has an `addr:street` tag, then Nominatim will first
-try to find a street with the same name before falling back to the closest
-street.
-
-There are also addresses in OSM, where the housenumber does not belong
-to a street at all. These have an `addr:place` tag. For these places, Nominatim
-tries to find a place with the given name in the indexed places with an
-address rank between 16 and 25. If none is found, then the dependent place
-is attached to the closest place in that category and the addr:place name is
-added as *unlisted* place, which indicates to Nominatim that it needs to add
-it to the address output, no matter what. This special case is necessary to
-cover addresses that don't really refer to an existing object.
-
-When an address has both the `addr:street` and `addr:place` tag, then Nominatim
-assumes that the `addr:place` tag in fact should be the city part of the address
-and give the POI the usual street number address.
-
-Dependent places are only added to the global search index `search_name` when
-they have either a name themselves or when they have address tags that are not
-covered by the places that make up their address. The latter ensures that
-addresses are always searchable by those address tags.

-# Nominatim Test Suite
-
-This chapter describes the tests in the `/test` directory, how they are
-structured and how to extend them. For a quick introduction on how to run
-the tests, see the [Development setup chapter](Development-Environment.md).
-
-## Overall structure
-
-There are two kind of tests in this test suite. There are functional tests
-which test the API interface using a BDD test framework and there are unit
-tests for specific PHP functions.
-
-This test directory is sturctured as follows:
-
-```
- -+-   bdd         Functional API tests
-  | \
-  | +-  steps      Step implementations for test descriptions
-  | +-  osm2pgsql  Tests for data import via osm2pgsql
-  | +-  db         Tests for internal data processing on import and update
-  | +-  api        Tests for API endpoints (search, reverse, etc.)
-  |
-  +-   php         PHP unit tests
-  +-   python      Python unit tests
-  +-   testdb      Base data for generating API test database
-  +-   testdata    Additional test data used by unit tests
-```
-
-## PHP Unit Tests (`test/php`)
-
-Unit tests for PHP code can be found in the `php/` directory. They test selected
-PHP functions. Very low coverage.
-
-To execute the test suite run
-
-    cd test/php
-    UNIT_TEST_DSN='pgsql:dbname=nominatim_unit_tests' phpunit ../
-
-It will read phpunit.xml which points to the library, test path, bootstrap
-strip and sets other parameters.
-
-It will use (and destroy) a local database 'nominatim_unit_tests'. You can set
-a different connection string with e.g. UNIT_TEST_DSN='pgsql:dbname=foo_unit_tests'.
-
-## Python Unit Tests (`test/python`)
-
-Unit tests for Python code can be found in the `python/` directory. The goal is
-to have complete coverage of the Python library in `nominatim`.
-
-To execute the tests run
-
-    py.test-3 test/python
-
-or
-
-    pytest test/python
-
-The name of the pytest binary depends on your installation.
-
-## BDD Functional Tests (`test/bdd`)
-
-Functional tests are written as BDD instructions. For more information on
-the philosophy of BDD testing, see the
-[Behave manual](http://pythonhosted.org/behave/philosophy.html).
-
-The following explanation assume that the reader is familiar with the BDD
-notations of features, scenarios and steps.
-
-All possible steps can be found in the `steps` directory and should ideally
-be documented.
-
-### General Usage
-
-To run the functional tests, do
-
-    cd test/bdd
-    behave
-
-The tests can be configured with a set of environment variables (`behave -D key=val`):
-
- * `BUILDDIR` - build directory of Nominatim installation to test
- * `TEMPLATE_DB` - name of template database used as a skeleton for
-                   the test databases (db tests)
- * `TEST_DB` - name of test database (db tests)
- * `API_TEST_DB` - name of the database containing the API test data (api tests)
- * `API_TEST_FILE` - OSM file to be imported into the API test database (api tests)
- * `DB_HOST` - (optional) hostname of database host
- * `DB_PORT` - (optional) port of database on host
- * `DB_USER` - (optional) username of database login
- * `DB_PASS` - (optional) password for database login
- * `SERVER_MODULE_PATH` - (optional) path on the Postgres server to Nominatim
-                          module shared library file
- * `REMOVE_TEMPLATE` - if true, the template and API database will not be reused
-                       during the next run. Reusing the base templates speeds
-                       up tests considerably but might lead to outdated errors
-                       for some changes in the database layout.
- * `KEEP_TEST_DB` - if true, the test database will not be dropped after a test
-                    is finished. Should only be used if one single scenario is
-                    run, otherwise the result is undefined.
-
-Logging can be defined through command line parameters of behave itself. Check
-out `behave --help` for details. Also have a look at the 'work-in-progress'
-feature of behave which comes in handy when writing new tests.
-
-### API Tests (`test/bdd/api`)
-
-These tests are meant to test the different API endpoints and their parameters.
-They require to import several datasets into a test database. This is normally
-done automatically during setup of the test. The API test database is then
-kept around and reused in subsequent runs of behave. Use `behave -DREMOVE_TEMPLATE`
-to force a reimport of the database.
-
-The official test dataset is saved in the file `test/testdb/apidb-test-data.pbf`
-and compromises the following data:
-
- * Geofabrik extract of Liechtenstein
- * extract of Autauga country, Alabama, US (for tests against Tiger data)
- * additional data from `test/testdb/additional_api_test.data.osm`
-
-API tests should only be testing the functionality of the website PHP code.
-Most tests should be formulated as BDD DB creation tests (see below) instead.
-
-#### Code Coverage
-
-The API tests also support code coverage tests. You need to install
-[PHP_CodeCoverage](https://github.com/sebastianbergmann/php-code-coverage).
-On Debian/Ubuntu run:
-
-    apt-get install php-codecoverage php-xdebug
-
-Then run the API tests as follows:
-
-    behave api -DPHPCOV=<coverage output dir>
-
-The output directory must be an absolute path. To generate reports, you can use
-the [phpcov](https://github.com/sebastianbergmann/phpcov) tool:
-
-    phpcov merge --html=<report output dir> <coverage output dir>
-
-### DB Creation Tests (`test/bdd/db`)
-
-These tests check the import and update of the Nominatim database. They do not
-test the correctness of osm2pgsql. Each test will write some data into the `place`
-table (and optionally the `planet_osm_*` tables if required) and then run
-Nominatim's processing functions on that.
-
-These tests need to create their own test databases. By default they will be
-called `test_template_nominatim` and `test_nominatim`. Names can be changed with
-the environment variables `TEMPLATE_DB` and `TEST_DB`. The user running the tests
-needs superuser rights for postgres.
-
-### Import Tests (`test/bdd/osm2pgsql`)
-
-These tests check that data is imported correctly into the place table. They
-use the same template database as the DB Creation tests, so the same remarks apply.
-
-Note that most testing of the gazetteer output of osm2pgsql is done in the tests
-of osm2pgsql itself. The BDD tests are just there to ensure compatibility of
-the osm2pgsql and Nominatim code.

-# Tokenizers
-
-The tokenizer is the component of Nominatim that is responsible for
-analysing names of OSM objects and queries. Nominatim provides different
-tokenizers that use different strategies for normalisation. This page describes
-how tokenizers are expected to work and the public API that needs to be
-implemented when creating a new tokenizer. For information on how to configure
-a specific tokenizer for a database see the
-[tokenizer chapter in the Customization Guide](../customize/Tokenizers.md).
-
-## Generic Architecture
-
-### About Search Tokens
-
-Search in Nominatim is organised around search tokens. Such a token represents
-string that can be part of the search query. Tokens are used so that the search
-index does not need to be organised around strings. Instead the database saves
-for each place which tokens match this place's name, address, house number etc.
-To be able to distinguish between these different types of information stored
-with the place, a search token also always has a certain type: name, house number,
-postcode etc.
-
-During search an incoming query is transformed into a ordered list of such
-search tokens (or rather many lists, see below) and this list is then converted
-into a database query to find the right place.
-
-It is the core task of the tokenizer to create, manage and assign the search
-tokens. The tokenizer is involved in two distinct operations:
-
-* __at import time__: scanning names of OSM objects, normalizing them and
-  building up the list of search tokens.
-* __at query time__: scanning the query and returning the appropriate search
-  tokens.
-
-
-### Importing
-
-The indexer is responsible to enrich an OSM object (or place) with all data
-required for geocoding. It is split into two parts: the controller collects
-the places that require updating, enriches the place information as required
-and hands the place to Postgresql. The collector is part of the Nominatim
-library written in Python. Within Postgresql, the `placex_update`
-trigger is responsible to fill out all secondary tables with extra geocoding
-information. This part is written in PL/pgSQL.
-
-The tokenizer is involved in both parts. When the indexer prepares a place,
-it hands it over to the tokenizer to inspect the names and create all the
-search tokens applicable for the place. This usually involves updating the
-tokenizer's internal token lists and creating a list of all token IDs for
-the specific place. This list is later needed in the PL/pgSQL part where the
-indexer needs to add the token IDs to the appropriate search tables. To be
-able to communicate the list between the Python part and the pl/pgSQL trigger,
-the `placex` table contains a special JSONB column `token_info` which is there
-for the exclusive use of the tokenizer.
-
-The Python part of the tokenizer returns a structured information about the
-tokens of a place to the indexer which converts it to JSON and inserts it into
-the `token_info` column. The content of the column is then handed to the PL/pqSQL
-callbacks of the tokenizer which extracts the required information. Usually
-the tokenizer then removes all information from the `token_info` structure,
-so that no information is ever persistently saved in the table. All information
-that went in should have been processed after all and put into secondary tables.
-This is however not a hard requirement. If the tokenizer needs to store
-additional information about a place permanently, it may do so in the
-`token_info` column. It just may never execute searches over it and
-consequently not create any special indexes on it.
-
-### Querying
-
-At query time, Nominatim builds up multiple _interpretations_ of the search
-query. Each of these interpretations is tried against the database in order
-of the likelihood with which they match to the search query. The first
-interpretation that yields results wins.
-
-The interpretations are encapsulated in the `SearchDescription` class. An
-instance of this class is created by applying a sequence of
-_search tokens_ to an initially empty SearchDescription. It is the
-responsibility of the tokenizer to parse the search query and derive all
-possible sequences of search tokens. To that end the tokenizer needs to parse
-the search query and look up matching words in its own data structures.
-
-## Tokenizer API
-
-The following section describes the functions that need to be implemented
-for a custom tokenizer implementation.
-
-!!! warning
-    This API is currently in early alpha status. While this API is meant to
-    be a public API on which other tokenizers may be implemented, the API is
-    far away from being stable at the moment.
-
-### Directory Structure
-
-Nominatim expects two files for a tokenizer:
-
-* `nominatim/tokenizer/<NAME>_tokenizer.py` containing the Python part of the
-  implementation
-* `lib-php/tokenizer/<NAME>_tokenizer.php` with the PHP part of the
-  implementation
-
-where `<NAME>` is a unique name for the tokenizer consisting of only lower-case
-letters, digits and underscore. A tokenizer also needs to install some SQL
-functions. By convention, these should be placed in `lib-sql/tokenizer`.
-
-If the tokenizer has a default configuration file, this should be saved in
-the `settings/<NAME>_tokenizer.<SUFFIX>`.
-
-### Configuration and Persistence
-
-Tokenizers may define custom settings for their configuration. All settings
-must be prefixed with `NOMINATIM_TOKENIZER_`. Settings may be transient or
-persistent. Transient settings are loaded from the configuration file when
-Nominatim is started and may thus be changed at any time. Persistent settings
-are tied to a database installation and must only be read during installation
-time. If they are needed for the runtime then they must be saved into the
-`nominatim_properties` table and later loaded from there.
-
-### The Python module
-
-The Python module is expect to export a single factory function:
-
-```python
-def create(dsn: str, data_dir: Path) -> AbstractTokenizer
-```
-
-The `dsn` parameter contains the DSN of the Nominatim database. The `data_dir`
-is a directory in the project directory that the tokenizer may use to save
-database-specific data. The function must return the instance of the tokenizer
-class as defined below.
-
-### Python Tokenizer Class
-
-All tokenizers must inherit from `nominatim.tokenizer.base.AbstractTokenizer`
-and implement the abstract functions defined there.
-
-::: nominatim.tokenizer.base.AbstractTokenizer
-    rendering:
-        heading_level: 4
-
-### Python Analyzer Class
-
-::: nominatim.tokenizer.base.AbstractAnalyzer
-    rendering:
-        heading_level: 4
-
-### PL/pgSQL Functions
-
-The tokenizer must provide access functions for the `token_info` column
-to the indexer which extracts the necessary information for the global
-search tables. If the tokenizer needs additional SQL functions for private
-use, then these functions must be prefixed with `token_` in order to ensure
-that there are no naming conflicts with the SQL indexer code.
-
-The following functions are expected:
-
-```sql
-FUNCTION token_get_name_search_tokens(info JSONB) RETURNS INTEGER[]
-```
-
-Return an array of token IDs of search terms that should match
-the name(s) for the given place. These tokens are used to look up the place
-by name and, where the place functions as part of an address for another place,
-by address. Must return NULL when the place has no name.
-
-```sql
-FUNCTION token_get_name_match_tokens(info JSONB) RETURNS INTEGER[]
-```
-
-Return an array of token IDs of full names of the place that should be used
-to match addresses. The list of match tokens is usually more strict than
-search tokens as it is used to find a match between two OSM tag values which
-are expected to contain matching full names. Partial terms should not be
-used for match tokens. Must return NULL when the place has no name.
-
-```sql
-FUNCTION token_get_housenumber_search_tokens(info JSONB) RETURNS INTEGER[]
-```
-
-Return an array of token IDs of house number tokens that apply to the place.
-Note that a place may have multiple house numbers, for example when apartments
-each have their own number. Must be NULL when the place has no house numbers.
-
-```sql
-FUNCTION token_normalized_housenumber(info JSONB) RETURNS TEXT
-```
-
-Return the house number(s) in the normalized form that can be matched against
-a house number token text. If a place has multiple house numbers they must
-be listed with a semicolon as delimiter. Must be NULL when the place has no
-house numbers.
-
-```sql
-FUNCTION token_matches_street(info JSONB, street_tokens INTEGER[]) RETURNS BOOLEAN
-```
-
-Check if the given tokens (previously saved from `token_get_name_match_tokens()`)
-match against the `addr:street` tag name. Must return either NULL or FALSE
-when the place has no `addr:street` tag.
-
-```sql
-FUNCTION token_matches_place(info JSONB, place_tokens INTEGER[]) RETURNS BOOLEAN
-```
-
-Check if the given tokens (previously saved from `token_get_name_match_tokens()`)
-match against the `addr:place` tag name. Must return either NULL or FALSE
-when the place has no `addr:place` tag.
-
-
-```sql
-FUNCTION token_addr_place_search_tokens(info JSONB) RETURNS INTEGER[]
-```
-
-Return the search token IDs extracted from the `addr:place` tag. These tokens
-are used for searches by address when no matching place can be found in the
-database. Must be NULL when the place has no `addr:place` tag.
-
-```sql
-FUNCTION token_get_address_keys(info JSONB) RETURNS SETOF TEXT
-```
-
-Return the set of keys for which address information is provided. This
-should correspond to the list of (relevant) `addr:*` tags with the `addr:`
-prefix removed or the keys used in the `address` dictionary of the place info.
-
-```sql
-FUNCTION token_get_address_search_tokens(info JSONB, key TEXT) RETURNS INTEGER[]
-```
-
-Return the array of search tokens for the given address part. `key` can be
-expected to be one of those returned with `token_get_address_keys()`. The
-search tokens are added to the address search vector of the place, when no
-corresponding OSM object could be found for the given address part from which
-to copy the name information.
-
-```sql
-FUNCTION token_matches_address(info JSONB, key TEXT, tokens INTEGER[])
-```
-
-Check if the given tokens match against the address part `key`.
-
-__Warning:__ the tokens that are handed in are the lists previously saved
-from `token_get_name_search_tokens()`, _not_ from the match token list. This
-is an historical oddity which will be fixed at some point in the future.
-Currently, tokenizers are encouraged to make sure that matching works against
-both the search token list and the match token list.
-
-```sql
-FUNCTION token_get_postcode(info JSONB) RETURNS TEXT
-```
-
-Return the postcode for the object, if any exists. The postcode must be in
-the form that should also be presented to the end-user.
-
-```sql
-FUNCTION token_strip_info(info JSONB) RETURNS JSONB
-```
-
-Return the part of the `token_info` field that should be stored in the database
-permanently. The indexer calls this function when all processing is done and
-replaces the content of the `token_info` column with the returned value before
-the trigger stores the information in the database. May return NULL if no
-information should be stored permanently.
-
-### PHP Tokenizer class
-
-The PHP tokenizer class is instantiated once per request and responsible for
-analyzing the incoming query. Multiple requests may be in flight in
-parallel.
-
-The class is expected to be found under the
-name of `\Nominatim\Tokenizer`. To find the class the PHP code includes the file
-`tokenizer/tokenizer.php` in the project directory. This file must be created
-when the tokenizer is first set up on import. The file should initialize any
-configuration variables by setting PHP constants and then require the file
-with the actual implementation of the tokenizer.
-
-The tokenizer class must implement the following functions:
-
-```php
-public function __construct(object &$oDB)
-```
-
-The constructor of the class receives a database connection that can be used
-to query persistent data in the database.
-
-```php
-public function checkStatus()
-```
-
-Check that the tokenizer can access its persistent data structures. If there
-is an issue, throw an `\Exception`.
-
-```php
-public function normalizeString(string $sTerm) : string
-```
-
-Normalize string to a form to be used for comparisons when reordering results.
-Nominatim reweighs results how well the final display string matches the actual
-query. Before comparing result and query, names and query are normalised against
-this function. The tokenizer can thus remove all properties that should not be
-taken into account for reweighing, e.g. special characters or case.
-
-```php
-public function tokensForSpecialTerm(string $sTerm) : array
-```
-
-Return the list of special term tokens that match the given term.
-
-```php
-public function extractTokensFromPhrases(array &$aPhrases) : TokenList
-```
-
-Parse the given phrases, splitting them into word lists and retrieve the
-matching tokens.
-
-The phrase array may take on two forms. In unstructured searches (using `q=`
-parameter) the search query is split at the commas and the elements are
-put into a sorted list. For structured searches the phrase array is an
-associative array where the key designates the type of the term (street, city,
-county etc.) The tokenizer may ignore the phrase type at this stage in parsing.
-Matching phrase type and appropriate search token type will be done later
-when the SearchDescription is built.
-
-For each phrase in the list of phrases, the function must analyse the phrase
-string and then call `setWordSets()` to communicate the result of the analysis.
-A word set is a list of strings, where each string refers to a search token.
-A phrase may have multiple interpretations. Therefore a list of word sets is
-usually attached to the phrase. The search tokens themselves are returned
-by the function in an associative array, where the key corresponds to the
-strings given in the word sets. The value is a list of search tokens. Thus
-a single string in the list of word sets may refer to multiple search tokens.

-# Basic Architecture

-Nominatim provides geocoding based on OpenStreetMap data. It uses a PostgreSQL
-database as a backend for storing the data.
-
-There are three basic parts to Nominatim's architecture: the data import,
-the address computation and the search frontend.
-
-The __data import__ stage reads the raw OSM data and extracts all information
-that is useful for geocoding. This part is done by osm2pgsql, the same tool
-that can also be used to import a rendering database. It uses the special
-gazetteer output plugin in `osm2pgsql/src/output-gazetter.[ch]pp`. The result of
-the import can be found in the database table `place`.
-
-The __address computation__ or __indexing__ stage takes the data from `place`
-and adds additional information needed for geocoding. It ranks the places by
-importance, links objects that belong together and computes addresses and
-the search index. Most of this work is done in PL/pgSQL via database triggers
-and can be found in the files in the `sql/functions/` directory.
-
-The __search frontend__ implements the actual API. It takes search
-and reverse geocoding queries from the user, looks up the data and
-returns the results in the requested format. This part is written in PHP
-and can be found in the `lib/` and `website/` directories.
