+# Fallback Country Boundaries
+
+Each place is assigned a `country_code` and partition. Partitions derive from `country_code`.
+
+Nominatim imports two pre-generated files
+
+   * `data/country_name.sql` (country code, name, default language, partition)
+   * `data/country_osm_grid.sql` (country code, geometry)
+
+before creating places in the database. This helps with fast lookups and missing data (e.g. if the data the user wants to import doesn't contain any country places).
+
+The number of countries in the world can change (South Sudan created 2011, Germany reunification), so can their boundaries. This document explain how the pre-generated files can be updated.
+
+
+
+## Country code
+
+Each place is assigned a two letter country_code based on its location, e.g. `gb` for Great Britain. Or `NULL` if no suitable country is found (usually it's in open water then).
+
+In `sql/functions.sql: get_country_code(geometry)` the place's center is checked against
+
+   1. country places already imported from the user's data file. Places are imported by rank low-to-high. Lowest rank 2 is countries so most places should be matched. Still the data file might be incomplete.
+   2. if unmatched: OSM grid boundaries
+   3. if still unmatched: OSM grid boundaries, but allow a small distance
+
+
+
+## Partitions
+
+Each place is assigned partition, which is a number 0..250. 0 is fallback/other.
+
+During place indexing (`sql/functions.sql: placex_insert()`) a place is assigned the partition based on its country code (`sql/functions.sql: get_partition(country_code)`). It checks in the `country_name` table.
+
+Most countries have their own partition, some share a partition. Thus partition counts vary greatly.
+
+Several database tables are split by partition to allow queries to run against less indices and improve caching.
+
+   * `location_area_large_<partition>`
+   * `search_name_<partition>`
+   * `location_road_<partition>`
+
+
+
+
+
+## Data files
+
+### data/country_name.sql
+
+Export from existing database table plus manual changes. `country_default_language_code` most taken from [https://wiki.openstreetmap.org/wiki/Nominatim/Country_Codes](), see `utils/country_languages.php`.
+
+
+
+### data/country_osm_grid.sql
+
+`country_grid.sql` merges territories by country. Then uses `function.sql: quad_split_geometry` to split each country into multiple [Quadtree](https://en.wikipedia.org/wiki/Quadtree) polygons for faster point-in-polygon lookups.
+
+To visualize one country as geojson feature collection, e.g. for loading into [geojson.io](http://geojson.io/):

+# GB Postcodes
+
+
+The server [importing instructions](https://www.nominatim.org/release-docs/latest/admin/Import-and-Update/) allow optionally download [`gb_postcode_data.sql.gz`](https://www.nominatim.org/data/gb_postcode_data.sql.gz). This document explains how the file got created.
+
+## GB vs UK
+
+GB (Great Britain) is more correct as the Ordnance Survey dataset doesn't contain postcodes from Northern Ireland.
+
+## Importing separately after the initial import
+
+If you forgot to download the file, or have a new version, you can import it separately:
+
+1. Import the downloaded `gb_postcode_data.sql.gz` file.
+
+2. Run the SQL query `SELECT count(getorcreate_postcode_id(postcode)) FROM gb_postcode;`. This will update the search index.
+
+3. Run `utils/setup.php --calculate-postcodes` from the build directory. This will copy data form the `gb_postcode` table to the `location_postcodes` table.
+
+
+
+## Converting Code-Point Open data
+
+1. Download from [Code-Point® Open](https://www.ordnancesurvey.co.uk/business-and-government/products/code-point-open.html). It requires an email address where a download link will be send to.
+
+2. `unzip codepo_gb.zip`
+
+    Unpacked you'll see a directory of CSV files.
+
+        $ more codepo_gb/Data/CSV/n.csv
+        "N1 0AA",10,530626,183961,"E92000001","E19000003","E18000007","","E09000019","E05000368"
+        "N1 0AB",10,530559,183978,"E92000001","E19000003","E18000007","","E09000019","E05000368"
+
+    The coordinates are "Northings" and "Eastings" in [OSGB 1936](http://epsg.io/1314) projection. They can be projected to WGS84 like this
+
+        SELECT ST_AsText(ST_Transform(ST_SetSRID('POINT(530626 183961)'::geometry,27700), 4326));
+        POINT(-0.117872733220225 51.5394424719303)

+# US TIGER address data
+
+Convert [TIGER](https://www.census.gov/geo/maps-data/data/tiger.html)/Line dataset of the US Census Bureau to SQL files which can be imported by Nominatim. The created tables in the Nominatim database are separate from OpenStreetMap tables and get queried at search time separately.
+
+The dataset gets updated once per year. Downloading is prone to be slow (can take a full day) and converting them can take hours as well.
+
+Replace '2019' with the current year throughout.
+
+  1. Install the GDAL library and python bindings and the unzip tool
+
+        # Ubuntu:
+        sudo apt-get install python3-gdal unzip
+
+  2. Get the TIGER 2019 data. You will need the EDGES files
+     (3,233 zip files, 11GB total).
+
+         wget -r ftp://ftp2.census.gov/geo/tiger/TIGER2019/EDGES/
+
+  3. Convert the data into SQL statements. Adjust the file paths in the scripts as needed
+
+        cd data-sources/us-tiger
+        ./convert.sh <input-path> <output-path>
+
+  4. Maybe: package the created files

+## Add Wikipedia and Wikidata to Nominatim
+
+OSM contributors frequently tag items with links to Wikipedia and Wikidata. Nominatim can use the page ranking of Wikipedia pages to help indicate the relative importance of osm features. This is done by calculating an importance score between 0 and 1 based on the number of inlinks to an article for a location. If two places have the same name and one is more important than the other, the wikipedia score often points to the correct place. 
+
+These scripts extract and prepare both Wikipedia page rank and Wikidata links for use in Nominatim.  
+
+#### Create a new postgres DB for Processing
+
+Due to the size of initial and intermediate tables, processing can be done in an external database:
+```
+CREATE DATABASE wikiprocessingdb;
+```
+---
+Wikipedia
+---  
+
+Processing these data requires a large amount of disk space (~1TB) and considerable time (>24 hours).
+
+#### Import & Process Wikipedia tables
+
+This step downloads and converts [Wikipedia](https://dumps.wikimedia.org/) page data SQL dumps to postgreSQL files which can be imported and processed with pagelink information from Wikipedia language sites to calculate importance scores.
+
+- The script will processes data from whatever set of Wikipedia languages are specified in the initial languages array
+
+- Note that processing the top 40 Wikipedia languages can take over a day, and will add nearly 1TB to the processing database. The final output tables will be approximately 11GB and 2GB in size
+
+To download, convert, and import the data, then process summary statistics and compute importance scores, run:
+```
+./wikipedia_import.sh
+```
+---
+Wikidata
+---
+
+This script downloads and processes Wikidata to enrich the previously created Wikipedia tables for use in Nominatim.
+
+#### Import & Process Wikidata
+
+This step downloads and converts [Wikidata](https://dumps.wikimedia.org/wikidatawiki/) page data SQL dumps to postgreSQL files which can be processed and imported into Nominatim database. Also utilizes Wikidata Query Service API to discover and include place types.
+
+- Script presumes that the user has already processed Wikipedia tables as specified above
+
+- Script requires wikidata_place_types.txt and wikidata_place_type_levles.csv
+
+- script requires the [jq json parser](https://stedolan.github.io/jq/)
+
+- Script processes data from whatever set of Wikipedia languages are specified in the initial languages array
+
+- Script queries Wikidata Query Service API and imports all instances of place types listed in wikidata_place_types.txt
+
+- Script updates wikipedia_articles table with extracted wikidata 
+
+By including Wikidata in the wikipedia_articles table, new connections can be made on the fly from the Nominatim placex table to wikipedia_article importance scores. 
+
+To download, convert, and import the data, then process required items, run:
+``` 
+./wikidata_import.sh
+```

+## Wikidata place types and related OSM Tags
+
+Wikidata does not have any official ontologies, however the [DBpedia project](https://wiki.dbpedia.org/) has created an [ontology](https://wiki.dbpedia.org/services-resources/ontology) that covered [place types](http://mappings.dbpedia.org/server/ontology/classes/#Place). The table below used the DBpedia place ontology as a starting point, and is provided as a cross-reference to the relevant OSM tags.
+
+The Wikidata place types listed in the table below can be used in conjunction with the [Wikidata Query Service](https://query.wikidata.org/) to retrieve instances of those place types from the Wikidata knowledgebase. 
+
+```
+SELECT ?item ?lat ?lon
+WHERE {
+  ?item wdt:P31*/wdt:P279*wd:Q9430; wdt:P625 ?pt.
+  ?item p:P625?loc.
+  ?loc psv:P625?cnode.
+  ?cnode wikibase:geoLatitude?lat.
+  ?cnode wikibase:geoLongitude?lon.
+}
+```
+
+An example json return for all instances of the Wikidata item "Q9430" (Ocean) can be seen at [json](https://query.wikidata.org/bigdata/namespace/wdq/sparql?format=json&query=SELECT?item?lat?lon%20WHERE{?item%20wdt:P31*/wdt:P279*wd:Q9430;wdt:P625?pt.?item%20p:P625?loc.?loc%20psv:P625?cnode.?cnode%20wikibase:geoLatitude?lat.?cnode%20wikibase:geoLongitude?lon.})
+
+**NOTE** the OSM tags listed are those listed in the wikidata entries, and not all the possible matches for tags within OSM.

+### Future Work
+
+The Wikidata improvements to Nominatim can be further enhanced by:
+
+- continuing to add new Wikidata links to OSM objects
+- increasing the number of place types accounted for in the wikipedia_articles table
+- working to use place types in the wikipedia_article matching process

-# 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"

-
-### 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 choosen 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.
-
-You can now copy the project directory from the source machine to the new machine.
-If necessary, edit the `.env` file to point it to the restored database.
-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 copy the installed
-version into the `module` directory of your project directory. The installed
-copy can usually be found under `/usr/local/lib/nominatim/module/nominatim.so`.

-# 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 deamon 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.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    $args;
-    fastcgi_pass unix:/var/run/php-fpm.sock;
-    fastcgi_index index.php;
-    include fastcgi_params;
-}
-
-location ~ [^/]\.php(/|$) {
-    fastcgi_split_path_info ^(.+?\.php)(/.*)$;
-    if (!-f $document_root$fastcgi_script_name) {
-        return 404;
-    }
-    fastcgi_pass unix:/var/run/php-fpm.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/`.

+# Importing and Updating the Database
+
+The following instructions explain how to create a Nominatim database
+from an OSM planet file and how to keep the database up to date. It
+is assumed that you have already successfully installed the Nominatim
+software itself, if not return to the [installation page](Installation.md).
+
+## Configuration setup in settings/local.php
+
+The Nominatim server can be customized via the file `settings/local.php`
+in the build directory. Note that this is a PHP file, so it must always
+start like this:
+
+    <?php
+
+without any leading spaces.
+
+There are lots of configuration settings you can tweak. Have a look
+at `settings/default.php` for a full list. 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 `settings/local.php`:
+
+    @define('CONST_Osm2pgsql_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 40GB of free space.
+
+## Downloading additional data
+
+### Wikipedia 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:
+
+    cd $NOMINATIM_SOURCE_DIR/data
+    wget https://www.nominatim.org/data/wikipedia_article.sql.bin
+    wget https://www.nominatim.org/data/wikipedia_redirect.sql.bin
+
+Combined the 2 files are around 1.5GB and add around 30GB to the install
+size of Nominatim. They also increase the install time by an hour or so.
+
+*NOTE:* you'll need to download the Wikipedia rankings before performing
+the initial import of the data if you want the rankings applied to the
+loaded data.
+
+### Great Britain, USA postcodes
+
+Nominatim can use postcodes from an external source to improve searches that
+involve a GB or US postcode. This data can be optionally downloaded:
+
+    cd $NOMINATIM_SOURCE_DIR/data
+    wget https://www.nominatim.org/data/gb_postcode_data.sql.gz
+    wget https://www.nominatim.org/data/us_postcode_data.sql.gz
+
+## 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 32GB of RAM and around 800GB 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 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
+below. 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, the dynamic part of the database can be
+safely dropped using the following command:
+
+```
+./utils/setup.php --drop
+```
+
+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.
+
+### 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.de/) 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:
+
+* **settings/import-admin.style**
+  Only import administrative boundaries and places.
+* **settings/import-street.style**
+  Like the admin style but also adds streets.
+* **settings/import-address.style**
+  Import all data necessary to compute addresses down to house number level.
+* **settings/import-full.style**
+  Default style that also includes points of interest.
+
+The style can be changed with the configuration `CONST_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
+2018 planet and after using the `--drop` option. It also shows the time
+needed for the import on a machine with 32GB RAM, 4 CPUS and SSDs. 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     |    5h        |  190 GB    |   20 GB
+street    |   42h        |  400 GB    |  180 GB
+address   |   59h        |  500 GB    |  260 GB
+full      |   80h        |  575 GB    |  300 GB
+
+You can also customize the styles further. For an description of the
+style format see [the development section](../develop/Import.md).
+
+## Initial import of the data
+
+**Important:** first try the import with a small extract, for example from
+[Geofabrik](https://download.geofabrik.de).
+
+Download the data to import and load the data with the following command
+from the build directory:
+
+```sh
+./utils/setup.php --osm-file <data file> --all [--osm2pgsql-cache 28000] 2>&1 | tee setup.log
+```
+
+The `--osm2pgsql-cache` parameter is optional but strongly recommended for
+planet imports. It sets the node cache size for the osm2pgsql import part
+(see `-C` parameter in osm2pgsql help). As a rule of thumb, this should be
+about the same size as the file you are importing but never more than
+2/3 of RAM available. If your machine starts swapping reduce the size.
+
+Computing word frequency for search terms can improve the performance of
+forward geocoding in particular under high load as it helps PostgreSQL's query
+planner to make the right decisions. To recompute word counts run:
+
+```sh
+./utils/update.php --recompute-word-counts
+```
+
+This will take a couple of hours for a full planet installation. You can
+also defer that step to a later point in time when you realise that
+performance becomes an issue. Just make sure that updates are stopped before
+running this function.
+
+If you want to be able to search for places by their type through
+[special key phrases](https://wiki.openstreetmap.org/wiki/Nominatim/Special_Phrases)
+you also need to enable these key phrases like this:

+## Installing Tiger housenumber data for the US
+
+Nominatim is able to use the official [TIGER](https://www.census.gov/geo/maps-data/data/tiger.html)
+address set to complement the OSM house number data in the US. You can add
+TIGER data to your own Nominatim instance by following these steps. The
+entire US adds about 10GB to your database.
+
+  1. Get preprocessed TIGER 2019 data and unpack it into the
+     data directory in your Nominatim sources:
+
+        cd Nominatim/data
+        wget https://nominatim.org/data/tiger2019-nominatim-preprocessed.tar.gz
+        tar xf tiger2019-nominatim-preprocessed.tar.gz
+
+    `data-source/us-tiger/README.md` explains how the data got preprocessed.
+
+  2. Import the data into your Nominatim database:
+
+        ./utils/setup.php --import-tiger-data
+
+  3. Enable use of the Tiger data in your `settings/local.php` by adding:
+
+         @define('CONST_Use_US_Tiger_Data', true);
+
+  4. Apply the new settings:
+
+```sh
+    ./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
+```
+
+
+## Updates
+
+There are many different ways to update your Nominatim database.
+The following section describes how to keep it up-to-date with Pyosmium.
+For a list of other methods see the output of `./utils/update.php --help`.
+
+#### Installing the newest version of Pyosmium
+
+It is recommended to install Pyosmium via pip. Make sure to use python3.
+Run (as the same user who will later run the updates):
+
+```sh
+pip3 install --user osmium
+```
+
+Nominatim needs a tool called `pyosmium-get-updates` which comes with
+Pyosmium. You need to tell Nominatim where to find it. Add the
+following line to your `settings/local.php`:
+
+    @define('CONST_Pyosmium_Binary', '/home/user/.local/bin/pyosmium-get-changes');
+
+The path above is fine if you used the `--user` parameter with pip.
+Replace `user` with your user name.
+
+#### Setting up the update process
+
+Next the update 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 `settings/local.php`. For example, to use the daily country extracts
+diffs for Ireland from Geofabrik add the following:
+
+    // base URL of the replication service
+    @define('CONST_Replication_Url', 'https://download.geofabrik.de/europe/ireland-and-northern-ireland-updates');
+    // How often upstream publishes diffs
+    @define('CONST_Replication_Update_Interval', '86400');
+    // How long to sleep if no update found yet
+    @define('CONST_Replication_Recheck_Interval', '900');
+
+To set up the update process now run the following command:
+
+    ./utils/update.php --init-updates
+
+It outputs the date where updates will start. Recheck that this date is
+what you expect.
+
+The `--init-updates` command needs to be rerun whenever the replication service
+is changed.
+
+#### Updating Nominatim
+
+The following command will keep your database constantly up to date:
+
+    ./utils/update.php --import-osmosis-all
+
+(Note that even though the old name "import-osmosis-all" has been kept for compatibility reasons, Osmosis is not required to run this - it uses pyosmium behind the scenes.)
+
+If you have imported multiple country extracts and want to keep them
+up-to-date, have a look at the script in
+[issue #60](https://github.com/openstreetmap/Nominatim/issues/60).

-# 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://www.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, you can also add
-    importances after the import. Download the files, then run
-    `nominatim refresh --wiki-data --importance`. Updating importances for
-    a planet can 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://www.nominatim.org/data/gb_postcodes.csv.gz
-    wget https://www.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 datastructure 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.de/) 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).

-## Tuning the PostgreSQL database
+
+## Setup of the server
+
+### PostgreSQL tuning
 
 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)
+    shared_buffers (2GB)
+    maintenance_work_mem (10GB)
+    work_mem (50MB)
+    effective_cache_size (24GB)
     synchronous_commit = off
     checkpoint_segments = 100 # only for postgresql <= 9.4
-    max_wal_size = 1GB # postgresql > 9.4
     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.

+
+### Webserver setup
+
+The `website/` directory in the build directory contains the configured
+website. Include the directory into your webbrowser to serve php files
+from there.
+
+#### Configure for use with Apache
+
+Make sure your Apache configuration contains the required permissions for the
+directory and create an alias:
+
+    <Directory "/srv/nominatim/build/website">
+      Options FollowSymLinks MultiViews
+      AddType text/html   .php
+      DirectoryIndex search.php
+      Require all granted
+    </Directory>
+    Alias /nominatim /srv/nominatim/build/website
+
+`/srv/nominatim/build` should be replaced with the location of your
+build directory.
+
+After making changes in the apache config you need to restart apache.
+The website should now be available on http://localhost/nominatim.
+
+#### Configure for use with Nginx
+
+Use php-fpm as a deamon for serving PHP cgi. Install php-fpm together with nginx.
+
+By default php listens on a network socket. If you want it to listen to a
+Unix socket instead, change the pool configuration (`pool.d/www.conf`) as
+follows:
+
+    ; Comment out the tcp listener and add the unix socket
+    ;listen = 127.0.0.1:9000
+    listen = /var/run/php5-fpm.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.
+
+    root /srv/nominatim/build/website;
+    index search.php index.html;
+    location ~ [^/]\.php(/|$) {
+        fastcgi_split_path_info ^(.+?\.php)(/.*)$;
+        if (!-f $document_root$fastcgi_script_name) {
+            return 404;
+        }
+        fastcgi_pass unix:/var/run/php5-fpm.sock;
+        fastcgi_index search.php;
+        include fastcgi.conf;
+    }
+
+Restart the nginx and php5-fpm services and the website should now be available
+at `http://localhost/`.

-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`.
-
-
-## 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:
+This page describes database migrations necessary to update existing databases
+to newer versions of Nominatim.
 
-* 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.
-
-## 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
-```

+`psql nominatim` to enter command line mode.

-# Setting up the Nominatim UI
-
-Nominatim is a search API, it does not provide a website interface on its
-own. [nominatim-ui](https://github.com/osm-search/nominatim-ui) offers a
-small website for testing your setup and inspecting the database content.
-
-This section provides a quick start how to use nominatim-ui with your
-installation. For more details, please also have a look at the
-[README of nominatim-ui](https://github.com/osm-search/nominatim-ui/blob/master/README.md).
-
-## Installing nominatim-ui
-
-We provide regular releases of nominatim-ui that contain the packaged website.
-They do not need any special installation. Just download, configure
-and run it. Grab the latest release from
-[nominatim-ui's Github release page](https://github.com/osm-search/nominatim-ui/releases)
-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 yo 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 explicity requested, forward to the UI.
-  RewriteCond %{QUERY_STRING} "format=html"
-  RewriteRule ^([^/]+).php ui/$1.html [R,END]
-  # Same but .php suffix is missing.
-  RewriteCond %{QUERY_STRING} "format=html"
-  RewriteRule ^([^/]+) 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]
-  # Same but .php suffix is missing.
-  RewriteCond %{QUERY_STRING} "!format="
-  RewriteCond %{REQUEST_URI}  "!/lookup"
-  RewriteCond %{REQUEST_URI}  "!/reverse"
-  RewriteRule ^([^/]+) 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-update.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-mainenance" ]; then
-    rm /srv/nominatim/schedule-mainenance
-    nominatim refresh --postcodes
-  fi
-done
-```
-
-A cron job then creates the file `/srv/nominatim/need-mainenance` once per night.
-
-
-#### 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 unexpectely 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.

 # 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.
-
+Reverse geocoding generates an address from a latitude and longitude or from
+an OSM object.

-# 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
- 22-24       | neighbourhood
- 25          | squares, farms, localities
- 26-27       | street
- 28-30       | POI/house number
-
-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.

-| 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_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.

-| --------------     | --------------------------------------------------- |
-| **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
-:    Indexes on the data tables for search term and address computation.
-     Used only for import and updates.
-
-NOMINATIM_TABLESPACE_AUX_DATA
-:    Auxiliary data tables for non-OSM data, e.g. for Tiger house number data.
-
-NOMINATIM_TABLESPACE_AUX_INDEX
-:    Indexes on auxiliary data tables.

-### Replication Update Settings
-
-#### NOMINATIM_REPLICATION_URL
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Base URL of the replication service |
-| **Format:**        | url |
-| **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.
-
-### API Settings
-
-#### NOMINATIM_CORS_NOACCESSCONTROL
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Send permissive CORS access headers |
-| **Format:**        | boolean |
-| **Default:**       | yes |
-| **After Changes:** | run `nominatim refresh --website` |
-
-When this setting is enabled, API HTTP responses include the HTTP
-[CORS](https://en.wikipedia.org/wiki/CORS) headers
-`access-control-allow-origin: *` and `access-control-allow-methods: OPTIONS,GET`.
-
-#### NOMINATIM_MAPICON_URL
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | URL prefix for static icon images |
-| **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`
-directory of the project available under a public URL and point this setting
-to the directory.
-
-
-#### NOMINATIM_DEFAULT_LANGUAGE
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **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.
-
-
-#### NOMINATIM_SEARCH_BATCH_MODE
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Enable a special batch query mode |
-| **Format:**        | boolean |
-| **Default:**       | no |
-| **After Changes:** | run `nominatim refresh --website` |
-
-This feature is currently undocumented and potentially broken.
-
-
-#### NOMINATIM_SEARCH_NAME_ONLY_THRESHOLD
-
-| 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            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Maximum number of OSM ids accepted by /lookup |
-| **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.
-
-
-#### NOMINATIM_POLYGON_OUTPUT_MAX_TYPES
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **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.
-
-### Logging Settings
-
-#### NOMINATIM_LOG_DB
-
-| Summary            |                                                     |
-| --------------     | --------------------------------------------------- |
-| **Description:**   | Log requests into the database |
-| **Format:**        | boolean |
-| **Default:**       | no |
-| **After Changes:** | run `nominatim refresh --website` |
-
-Enable logging requests into a database table with this setting. The logs
-can be found in the table `new_query_log`.
-
-When using this logging method, it is advisable to set up a job that
-regularly clears out old logging information. Nominatim will not do that
-on its own.
-
-Can be used as the same time as NOMINATIM_LOG_FILE.
-

-
-
-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 ms and corresponds to the time the query took executing in PHP.
-type contains the name of the endpoint used.
-
-Can be used as the same time as NOMINATIM_LOG_DB.

-# Special phrases
-
-## Importing OSM user-maintained special phrases
-
-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
-removing the other ones.

-# 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 currently the default.
-
-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.
-
-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
-```
-
-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.
-
-##### split-name-list
-
-::: nominatim.tokenizer.sanitizers.split_name_list
-    selection:
-        members: False
-    rendering:
-        heading_level: 6
-
-##### strip-brace-terms
-
-::: nominatim.tokenizer.sanitizers.strip_brace_terms
-    selection:
-        members: False
-    rendering:
-        heading_level: 6
-
-##### tag-analyzer-by-language
-
-::: nominatim.tokenizer.sanitizers.tag_analyzer_by_language
-    selection:
-        members: False
-    rendering:
-        heading_level: 6
-
-
-
-#### 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.
-
-Different analyzer implementations may exist. To select the implementation,
-the `analyzer` parameter must be set. Currently there is only one implementation
-`generic` which is described in the following.
-
-##### Generic token analyzer
-
-The generic analyzer is able to create variants from a list of given
-abbreviation and decomposition replacements. It takes one optional parameter
-`variants` which lists the replacements to apply. If the section is
-omitted, then the generic analyzer becomes a simple analyzer that only
-applies the transliteration.
-
-The 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`.
-
-### 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 useable 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
-
-## Auxilary data tables
-
-Finally there are some table for auxillary 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 developement
-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) >= 7.3
-* [PHP CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer)
-* [Pylint](https://pylint.org/) (2.6.0 is used for the CI)
-* [pytest](https://pytest.org)
-
-The documentation is built with mkdocs:
-
-* [mkdocs](https://www.mkdocs.org/) >= 1.1.2
-* [mkdocstrings](https://mkdocstrings.github.io/)
-
-### 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 pylint
-
-pip3 install --user behave mkdocs mkdocstrings pytest
-```
-
-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
-
-```

+# OSM Data Import
+
+OSM data is initially imported using osm2pgsql. Nominatim uses its own data
+output style 'gazetteer', which differs from the output style created for
+map rendering.
+
+## Database Layout
+
+The gazetteer style produces a single table `place` with the following rows:
+
+ * `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`).
+
 ## Configuring the Import

-# 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](Tokenizer.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.

+# Place Ranking in Nominatim
+
+Nominatim uses two metrics to rank a place: search rank and address rank.
+Both can be assigned a value between 0 and 30. They serve slightly
+different purposes, which are explained in this chapter.
+
+## Search rank
+
+The search rank describes the extent and importance of a place. It is used
+when ranking search result. 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.
+
+## 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. All other objects have an address rank
+of 0.
+
+Note that the search rank of a place plays a role in the address computation
+as well. When collecting the places that should make up the address parts
+then only places are taken into account that have a lower address rank than
+the search rank of the base object.
+
+## 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
+defined with `CONST_Address_Level_Config` according to their type and
+the country they are in.
+
+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 counrty/key/value appears only once per
+file. Otherwise the import will fail with a UNIQUE INDEX constraint violation
+on import.

-# 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:
-
-* `nominiatim/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 Persistance
-
-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_normalized_postcode(postcode TEXT) RETURNS TEXT
-```
-
-Return the normalized version of the given postcode. This function must return
-the same value as the Python function `AbstractAnalyzer->normalize_postcode()`.
-
-```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.

-# Additional Data Sources
-
-This guide explains how data sources other than OpenStreetMap mentioned in
-the install instructions got obtained and converted.
-
-## Country grid
-
-Nominatim uses pre-generated country borders data. In case one imports only
-a subset of a country. And to assign each place a partition. Nominatim
-database tables are split into partitions for performance.
-
-More details in [osm-search/country-grid-data](https://github.com/osm-search/country-grid-data).
-
-## US Census TIGER
-
-For the United States you can choose to import additonal street-level data.
-The data isn't mixed into OSM data but queried as fallback when no OSM
-result can be found.
-
-More details in [osm-search/TIGER-data](https://github.com/osm-search/TIGER-data).
-
-## GB postcodes
-
-For Great Britain you can choose to import Royalmail postcode centroids.
-
-More details in [osm-search/gb-postcode-data](https://github.com/osm-search/gb-postcode-data).
-
-
-## Wikipedia & Wikidata rankings
-
-Nominatim can import "importance" data of place names. This greatly
-improves ranking of results.
-
-More details in [osm-search/wikipedia-wikidata](https://github.com/osm-search/wikipedia-wikidata).
