[special key phrases](https://wiki.openstreetmap.org/wiki/Nominatim/Special_Phrases)
you also need to import these key phrases like this:
nominatim special-phrases --import-from-wiki
```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 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 2 previous commands will update the phrases from your database.
This mean 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.
