+title: ''
+labels: ''
+assignees: ''
+
+---
+
+## What did you search for?
+
+Please try to provide a link to your search. You  can go to https://nominatim.openstreetmap.org and repeat your search there. If you originally found the issue somewhere else, please tell us what software/website you were using.
+
+## What result did you get?
+
+## What result did you expect?
+
+**Is the result in the right place and just named wrongly?** 
+
+Please tell us the display name you expected.
+
+**Is the result missing completely?**
+
+Make sure that the data you are looking for is in OpenStreetMap. Provide a link to the OpenStreetMap object or if you cannot get it, a link to the map on https://openstreetmap.org where you expect the result to be.
+
+To get the link to the OSM object, you can try the following:
+
+ * Go to [https://openstreetmap.org](https://openstreetmap.org).
+ * Move to the area of the map where you expect the result and then zoom in as much as possible.
+ * Click on the question mark on the right side of the map. You get a question cursor. Use it to click on the map where your object is located.
+ * Find the object of interest in the list that appears on the left side.
+ * Click on the object and report back the URL that the browser shows.
+
+## Further details

+# 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
+
+To import multiple regions in your database, you need to configure and run `utils/import_multiple_regions.sh` file. This script will set up the update directory which has the following structure:
+
+```bash
+update
+    ├── europe
+    │   ├── andorra
+    │   │   └── sequence.state
+    │   └── monaco
+    │       └── sequence.state
+    └── tmp
+        ├── combined.osm.pbf
+        └── europe
+                ├── andorra-latest.osm.pbf
+                └── monaco-latest.osm.pbf
+
+
+```
+
+The `sequence.state` files will contain the sequence ID, which will be used by pyosmium to get updates. The tmp folder is used for import dump.
+
+### Configuring multiple regions
+
+The file `import_multiple_regions.sh` needs to be edited as per your requirement:
+
+1. List of countries. eg:
+
+        COUNTRIES="europe/monaco europe/andorra"
+
+2. Path to Build directory. eg:
+
+        NOMINATIMBUILD="/srv/nominatim/build"
+
+3. Path to Update directory. eg:
+        
+        UPDATEDIR="/srv/nominatim/update"
+
+4. Replication URL. eg:
+    
+        BASEURL="https://download.geofabrik.de"
+        DOWNCOUNTRYPOSTFIX="-latest.osm.pbf"
+ 
+!!! tip
+    If your database already exists and you want to add more countries, replace the setting up part
+    `${SETUPFILE} --osm-file ${UPDATEDIR}/tmp/combined.osm.pbf --all 2>&1`
+    with `${UPDATEFILE} --import-file ${UPDATEDIR}/tmp/combined.osm.pbf --index --index-instances N 2>&1`
+    where N is the numbers of CPUs in your system.
+
+### Setting up multiple regions
+
+Run the following command from your Nominatim directory after configuring the file.
+
+    bash ./utils/import_multiple_regions.sh
+
+!!! danger "Important"
+        This file uses osmium-tool. It must be installed before executing the import script.
+        Installation instructions can be found [here](https://osmcode.org/osmium-tool/manual.html#installation).
+
+### Updating multiple regions
+
+To import multiple regions in your database, you need to configure and run ```utils/update_database.sh```.
+This uses the update directory set up while setting up the DB.   
+
+### Configuring multiple regions
+
+The file `update_database.sh` needs to be edited as per your requirement:
+
+1. List of countries. eg:
+
+        COUNTRIES="europe/monaco europe/andorra"
+
+2. Path to Build directory. eg:
+
+        NOMINATIMBUILD="/srv/nominatim/build"
+
+3. Path to Update directory. eg:
+        
+        UPDATEDIR="/srv/nominatim/update"
+
+4. Replication URL. eg:
+    
+        BASEURL="https://download.geofabrik.de"
+        DOWNCOUNTRYPOSTFIX="-updates"
+
+5. Followup can be set according to your installation. eg: For Photon,
+
+        FOLLOWUP="curl http://localhost:2322/nominatim-update"
+
+    will handle the indexing.
+
+### Updating the database
+
+Run the following command from your Nominatim directory after configuring the file.
+
+    bash ./utils/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.
+
+## Importing Nominatim to 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.
+
+### 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 nomrmalization 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 `settings/local.php` file:
+
+```php
+@define('CONST_Database_Module_Path', '<directory on the database server where nominatim.so resides>');
+```
+
+Now change the `CONST_Database_DSN` to point to your remote server and continue
+to follow the [standard instructions for importing](/admin/Import).

+# Deploying Nominatim
+
+The Nominatim API is implemented as a PHP application. The `website/` directory
+in the build 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 build directory is
+    located in `/srv/nominatim/build` and the source code in
+    `/srv/nominatim/Nominatim`. 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/build/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 "/srv/nominatim/Nominatim/(website|lib|settings)(/.*)?"
+sudo semanage fcontext -a -t httpd_sys_content_t "/srv/nominatim/build/(website|settings)(/.*)?"
+sudo semanage fcontext -a -t lib_t "/srv/nominatim/build/module/nominatim.so"
+sudo restorecon -R -v /srv/nominatim/Nominatim
+sudo restorecon -R -v /srv/nominatim/build
+```
+
+## 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/build/website">
+  Options FollowSymLinks MultiViews
+  AddType text/html   .php
+  DirectoryIndex search.php
+  Require all granted
+</Directory>
+Alias /nominatim /srv/nominatim/build/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/build/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.
-
-### UK postcodes
-
-Nominatim can use postcodes from an external source to improve searches that involve a UK postcode. This data can be optionally downloaded: 
-
-    cd $NOMINATIM_SOURCE_DIR/data
-    wget https://www.nominatim.org/data/gb_postcode_data.sql.gz
-
-
-## Initial import of the data
-
-**Important:** first try the import with a small excerpt, for example from
-[Geofabrik](https://download.geofabrik.de).
-
-Download the data to import and load the data with the following command:
-
-```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 Postgres' 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:
-
-    ./utils/specialphrases.php --wiki-import > specialphrases.sql
-    psql -d nominatim -f specialphrases.sql
-
-Note that this command downloads the phrases from the wiki link above.

-## Installing Tiger housenumber data for the US
-
-Nominatim is able to use the official TIGER 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:
-
-  1. Install the GDAL library and python bindings and the unzip tool
-
-       * Ubuntu: `sudo apt-get install python-gdal unzip`
-       * CentOS: `sudo yum install gdal-python unzip`
-
-  2. Get preprocessed TIGER 2017 data and unpack it into the
-     data directory in your Nominatim sources:
-
-        cd Nominatim/data
-        wget https://nominatim.org/data/tiger2017-nominatim-preprocessed.tar.gz
-        tar xf tiger2017-nominatim-preprocessed.tar.gz
-
-  3. Import the data into your Nominatim database: 
-
-        ./utils/setup.php --import-tiger-data
-
-  4. Enable use of the Tiger data in your `settings/local.php` by adding:
-
-         @define('CONST_Use_US_Tiger_Data', true);
-
-  5. Apply the new settings:
-
-```sh
-    ./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
-```
-
-The entire US adds about 10GB to your database.
-
-You can also process the data from the original TIGER data to create the
-SQL files, Nominatim needs for the import:
-
-  1. Get the TIGER 2017 data. You will need the EDGES files
-     (3,234 zip files, 11GB total).
-
-         wget -r ftp://ftp2.census.gov/geo/tiger/TIGER2017/EDGES/
-
-  2. Convert the data into SQL statements: 
-
-         ./utils/imports.php --parse-tiger <tiger edge data directory>
-
-Be warned that this can take quite a long time. After this process is finished,
-the same preprocessed files as above are available in `data/tiger`.
-
-## Updates
-
-There are many different possibilities 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. Run (as the same user who
-will later run the updates):
-
-```sh
-pip 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.)
-

+# Importing 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 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:
+
+    cd $NOMINATIM_SOURCE_DIR/data
+    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
+    `./utils/setup.php --import-wikipedia-articles`
+    and `./utils/update.php --recompute-importance`.
+
+### 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 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). 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.
+* **settings/import-extratags.style**
+  Like the full style but also adds most of the OSM tags into the extratags
+  column.
+
+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
+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](../develop/Import.md#configuring-the-import) 
+can be found in the development section.
+
+## 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 **build directory** to start the import:
+
+```sh
+./utils/setup.php --osm-file <data file> --all 2>&1 | tee setup.log
+```
+
+### 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#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.
+
+### Verify the import
+
+Run this script to verify all required tables and indices got created successfully.
+
+```sh
+./utils/check_import_finished.php
+```
+
+### Setting up the website
+
+Run the following command to set up the configuration file for the API frontend
+`settings/settings-frontend.php`. These settings are used in website/*.php files.
+
+```sh
+./utils/setup.php --setup-website
+```
+!!! Note
+    This step is not necessary if you use `--all` option while setting up the DB.
+
+Now you can try out your installation by running:
+
+```sh
+make 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`.
+
+To run Nominatim via webservers like Apache or nginx, please read the
+[Deployment chapter](Deployment.md).
+
+## Tuning the database
+
+Accurate word frequency information for search terms helps PostgreSQL's query
+planner to make the right decisions. Recomputing them can improve the performance
+of forward geocoding in particular under high load. 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:
+
+    ./utils/specialphrases.php --wiki-import > specialphrases.sql
+    psql -d nominatim -f specialphrases.sql
+
+Note that this command downloads the phrases from the wiki link above. You
+need internet access for the step.
+
+
+## Installing Tiger housenumber data for the US
+
+Nominatim is able to use the official [TIGER](https://www.census.gov/geographies/mapping-files/time-series/geo/tiger-line-file.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
+
+  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
+```
+
+
+See the [developer's guide](../develop/data-sources.md#us-census-tiger) for more
+information on how the data got preprocessed.

-### Webserver setup
-
-The `website/` directory in the build directory contains the configured

-
-#### Configure for use with Apache
-
-Make sure your Apache configuration contains the required permissions for the

-    <Directory "/srv/nominatim/build/website">
-      Options FollowSymLinks MultiViews
-      AddType text/html   .php

+## Downloading and building Nominatim
+
+### Downloading the latest release
+
+You can download the [latest release from nominatim.org](https://nominatim.org/downloads/).
+The release contains all necessary files. Just unpack it.
+
+### Downloading the latest development version
+
+If you want to install latest development version from github, make sure to
+also check out the osm2pgsql subproject:
+
+```
+git clone --recursive git://github.com/openstreetmap/Nominatim.git
+```
+
+The development version does not include the country grid. Download it separately:
+
+```
+wget -O Nominatim/data/country_osm_grid.sql.gz https://www.nominatim.org/data/country_grid.sql.gz
+```
+
+### Building Nominatim
+
+The code must be built in a separate directory. Create the directory and
+change into it.
+
+```
+mkdir build
+cd build
+```
+
+Nominatim uses cmake and make for building. Assuming that you have created the
+build at the same level as the Nominatim source directory run:
+
+```
+cmake ../Nominatim
+make
+```
+
+Now continue with [importing the database](Import.md).

+
+### 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`;

+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) 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
+```
+
+## 3.4.0 -> 3.5.0
+
+### New Wikipedia/Wikidata importance tables
+
+The `wikipedia_*` tables have a new format that also includes references to
+Wikidata. You need to update the computation functions and the tables as
+follows:
+
+  * download the new Wikipedia tables as described in the import section
+  * reimport the tables: `./utils/setup.php --import-wikipedia-articles`
+  * update the functions: `./utils/setup.php --create-functions --enable-diff-updates`
+  * create a new lookup index:
+```sql
+CREATE INDEX idx_placex_wikidata
+  ON placex
+  USING BTREE ((extratags -> 'wikidata'))
+  WHERE extratags ? 'wikidata'
+    AND class = 'place'
+    AND osm_type = 'N'
+    AND rank_search < 26;
+```
+  * compute importance: `./utils/update.php --recompute-importance`
+
+The last step takes about 10 hours on the full planet.
+
+Remove one function (it will be recreated in the next step):
+
+```sql
+DROP FUNCTION create_country(hstore,character varying);
+```
+
+Finally, update all SQL functions:
+
+```sh
+./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
+```
+
+## 3.3.0 -> 3.4.0
+
+### Reorganisation of location_area_country table
+
+The table `location_area_country` has been optimized. You need to switch to the
+new format when you run updates. While updates are disabled, run the following
+SQL commands:
+
+```sql
+CREATE TABLE location_area_country_new AS
+  SELECT place_id, country_code, geometry FROM location_area_country;
+DROP TABLE location_area_country;
+ALTER TABLE location_area_country_new RENAME TO location_area_country;
+CREATE INDEX idx_location_area_country_geometry ON location_area_country USING GIST (geometry);
+CREATE INDEX idx_location_area_country_place_id ON location_area_country USING BTREE (place_id);

+# 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
+
+nominatim-ui does not need any special installation, just download, configure
+and run it.
+
+Clone the source from github:
+
+    git clone https://github.com/osm-search/nominatim-ui
+
+Copy the example configuration into the right place:
+
+    cd nominatim-ui
+    cp dist/config.example.js dist/config.js
+
+Now adapt the configuration to your needs. You need at least
+to change the `Nominatim_API_Endpoint` to point to your Nominatim installation.
+
+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 with Pyosmium.
+For a list of other methods see the output of `./utils/update.php --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
+
+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-changes` 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, [Advanced installations section](Advanced-Installations.md) contains instructions 
+to set up and update multiple country extracts.

+
+## Notes on field values
+
+### place_id is not a persistent id
+
+The `place_id` is an internal identifier that is assigned data is imported
+into a Nominatim database. The same OSM object will have a different value
+on another server. It may even change its ID on the same server when it is
+removed and reimported while updating the database with fresh OSM data.
+It is thus not useful to treat it as permanent for later use.
+
+The combination `osm_type`+`osm_id` is slighly better but remember in
+OpenStreetMap mappers can delete, split, recreate places (and those
+get a new `osm_id`), there is no link between those old and new ids.
+Places can also change their meaning without changing their `osm_id`,
+e.g. when a restaurant is retagged as supermarket. For a more in-depth
+discussion see [Permanent ID](https://wiki.openstreetmap.org/wiki/Permanent_ID).
+
+If you need an ID that is consistent over multiple installations of Nominatim,
+then you should use the combination of `osm_type`+`osm_id`+`class`.
+
+### OSM reference
+
+Nominatim may sometimes return special objects that do not correspond directly
+to an object in OpenStreetMap. These are:
+
+* **Postcodes**. Nominatim returns an postcode point created from all mapped
+  postcodes of the same name. The class and type of these object is `place=postcdode`.
+  No `osm_type` and `osm_id` are included in the result.
+* **Housenumber interpolations**. Nominatim returns a single interpolated
+  housenumber from the interpolation way. The class and type are `place=house`
+  and `osm_type` and `osm_id` correspond to the interpolation way in OSM.
+* **TIGER housenumber.** Nominatim returns a single interpolated housenumber
+  from the TIGER data. The class and type are `place=house`
+  and `osm_type` and `osm_id` correspond to the street mentioned in the result.
+
+Please note that the `osm_type` and `osm_id` returned may be changed in the
+future. You should not expect to only find `node`, `way` and `relation` for
+the type.

+Bounds crossing the antimeridian have a min latitude -180 and max latitude 180,
+essentially covering the entire planet
+(see [issue 184](https://github.com/openstreetmap/Nominatim/issues/184)).
+
+### addressdetails
+
+Address details in the xml and json formats return a list of names together
+with a designation label. Per default the following labels may appear:
+
+ * continent
+ * country, country_code
+ * region, state, state_district, county
+ * municipality, city, town, village
+ * city_district, district, borough, suburb, subdivision
+ * hamlet, croft, isolated_dwelling
+ * neighbourhood, allotments, quarter
+ * city_block, residental, farm, farmyard, industrial, commercial, retail
+ * road
+ * house_number, house_name
+ * emergency, historic, military, natural, landuse, place, railway,
+   man_made, aerialway, boundary, amenity, aeroway, club, craft, leisure,
+   office, mountain_pass, shop, tourism, bridge, tunnel, waterway
+
+They roughly correspond to the classification of the OpenStreetMap data
+according to either the `place` tag or the main key of the object.

 # Reverse Geocoding
 
-Reverse geocoding generates an address from a latitude and longitude or from
-an OSM object.
+Reverse geocoding generates an address from a latitude and longitude.
+
+## How it works
+
+The reverse geocoding API does not exactly compute the address for the
+coordinate it receives. It works by finding the closest suitable OSM object
+and returning its address information. This may occasionally lead to
+unexpected results.
+
+First of all, Nominatim only includes OSM objects in
+its index that are suitable for searching. Small, unnamed paths for example
+are missing from the database and can therefore not be used for reverse
+geocoding either.
+
+The other issue to be aware of is that the closest OSM object may not always
+have a similar enough address to the coordinate you were requesting. For
+example, in dense city areas it may belong to a completely different street.
+
 
 ## Parameters
 
 The main format of the reverse API is
 
 ```
-https://nominatim.openstreetmap.org/reverse?<query>
+https://nominatim.openstreetmap.org/reverse?lat=<value>&lon=<value>&<params>
 ```
 
-There are two ways how the requested location can be specified:
+where `lat` and `lon` are latitude and longitutde of a coordinate in WGS84
+projection. The API returns exactly one result or an error when the coordinate
+is in an area with no OSM data coverage.
 
-* `lat=<value>` `lon=<value>`
+Additional paramters are accepted as listed below.
 
-    A geographic location to generate an address for. The coordiantes must be
-    in WGS84 format.
-
-* `osm_type=[N|W|R]` `osm_id=<value>`
-
-    A specific OSM node(N), way(W) or relation(R) to return an address for.
-
-In both cases exactly one object is returned. The two input paramters cannot
-be used at the same time. Both accept the additional optional parameters listed
-below.

+# 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). It has the following additional requirements:
+
+* [behave test framework](https://behave.readthedocs.io) >= 1.2.5
+* [nose](https://nose.readthedocs.io)
+* [phpunit](https://phpunit.de) >= 7.3
+* [PHP CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer)
+
+The documentation is built with mkdocs:
+
+* [mkdocs](https://www.mkdocs.org/) >= 1.1.2
+
+### Installing prerequisites on Ubuntu/Debian
+
+Some of the Python packages require the newest version which is not yet
+available with the current distributions. Therefore it is recommended to
+install pip to get the newest versions.
+
+To install all necessary packages run:
+
+```sh
+sudo apt install php-cgi phpunit php-codesniffer \
+                 python3-pip python3-setuptools python3-dev
+
+pip3 install --user behave nose mkdocs
+```
+
+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.
+
+### Preparing the test database
+
+Some of the behavioural test expect a test database to be present. You need at
+least 2GB RAM and 10GB disk space to create the database.
+
+First create a separate directory for the test DB and fetch the test planet
+data and the Tiger data for South Dakota:
+
+```
+mkdir testdb
+cd testdb
+wget https://www.nominatim.org/data/test/nominatim-api-testdata.pbf
+wget -O - https://nominatim.org/data/tiger2018-nominatim-preprocessed.tar.gz | tar xz --wildcards --no-anchored '46*'
+```
+
+Configure and build Nominatim in the usual way:
+
+```
+cmake $USERNAME/Nominatim
+make
+```
+
+Copy the test settings:
+
+```
+cp $USERNAME/Nominatim/test/testdb/local.php settings/
+```
+
+Inspect the file to check that all settings are correct for your local setup.
+
+Now you can import the test database:
+
+```
+dropdb --if-exists test_api_nominatim
+./utils/setup.php --all --osm-file nominatim-api-testdb.pbf 2>&1 | tee import.log
+./utils/specialphrases.php --wiki-import | psql -d test_api_nominatim 2>&1 | tee -a import.log
+./utils/setup.php --import-tiger-data 2>&1 | tee -a import.log
+```
+
+### Running the tests
+
+To run all tests just go to the test directory and run make:
+
+```sh
+cd test
+make
+```
+
+To skip tests that require the test database, run `make no-test-db` instead.
+
+For more information about the structure of the tests and how to change and
+extend the test suite, see the [Testing chapter](Testing.md).
+
+## Documentation Pages
+
+The [Nominatim documentation](https://nominatim.org/release-docs/develop/) is
+built using the [MkDocs](https://www.mkdocs.org/) static site generation
+framework. The master branch is automatically deployed every night on
+[https://nominatim.org/release-docs/develop/](https://nominatim.org/release-docs/develop/)
+
+To build the documentation, go to the build directory and run
+
+```
+make doc
+INFO - Cleaning site directory
+INFO - Building documentation to directory: /home/vagrant/build/site-html
+```
+
+This runs `mkdocs build` plus extra transformation of some files and adds
+symlinks (see `CMakeLists.txt` for the exact steps).
+
+Now you can start webserver for local testing
+
+```
+build> mkdocs serve
+[server:296] Serving on http://127.0.0.1:8000
+[handlers:62] Start watching changes
+```
+
+If you develop inside a Vagrant virtual machine, use a port that is forwarded
+to your host:
+
+```
+build> mkdocs serve --dev-addr 0.0.0.0:8088
+[server:296] Serving on http://0.0.0.0:8088
+[handlers:62] Start watching changes

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

+
+The blog post
+[Nominatim and Postcodes](https://www.openstreetmap.org/user/lonvia/diary/43143)
+describes the handling implemented since Nominatim 3.1.
+
+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.
+
+
+## Regular updating calculated postcodes
+
+The script to rerun the calculation is
+`build/utils/update.php --calculate-postcodes`
+and runs once per night on nominatim.openstreetmap.org.
+
+
+## Finding places that share a specific postcode
+
+In the Nominatim database run
+
+```sql
+SELECT address->'postcode' as pc,
+       osm_type, osm_id, class, type,
+       st_x(centroid) as lon, st_y(centroid) as lat
+FROM placex
+WHERE country_code='fr'
+  AND upper(trim (both ' ' from address->'postcode')) = '33210';

+# 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 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
+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 country/key/value appears only once per
+file. Otherwise the import will fail with a UNIQUE INDEX constraint violation
+on import.

+
+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.
