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
+ wget https://nominatim.org/data/wikimedia-importance.sql.gz
The file is about 400MB and adds around 4GB to the Nominatim database.
!!! tip
- If you forgot to download the wikipedia rankings, 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.

+Now you can try out your installation by executing a simple query on the
+command line:
-```sh
+``` sh
+nominatim search --query Berlin
+```
+
+or, when you have a reverse-only installation:
+
+``` sh
+nominatim reverse --lat 51 --lon 45
+```
+
+If you want to run Nominatim as a service, you need to make a choice between
+running the modern Python frontend and the legacy PHP frontend.
+Make sure you have installed the right packages as per
+[Installation](Installation.md#software).
+
+#### Testing the Python frontend
+
+To run the test server against the Python frontend, you must choose a
+web framework to use, either starlette or falcon. Make sure the appropriate
+packages are installed. Then run
+
+``` 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`.
+or, if you prefer to use Starlette instead of Falcon as webserver,
+
+``` sh
+nominatim serve --engine starlette
+```
-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`.
+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`
+or, for reverse-only installations a reverse query,
+e.g. `http://localhost:8088/reverse.php?lat=27.1750090510034&lon=78.04209025`.

-## Tuning the database
+#### Testing the PHP frontend
-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:
+You can run a small test server with the PHP frontend like this:
```sh
-nominatim refresh --word-counts
+nominatim serve --engine php
```
-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.
+Go to `http://localhost:8088/status.php` and you should see the message `OK`.
