How to configure Nominatim?

Hi,

I would like to limit the list of OSM tags my Nominatim server makes use of. I found:

The file phrase_settings.php with a blacklist and a whitelist but the default values don't look as if they would be valid.
The file partitionedtags.def but it seems to be incomplete. E.g. boundary:postal_code is not in there but AFAIK Nominatim uses it.

I couldn't find any documentation. Anyone knows?

Best, Helge

One Answer:

There is no simple configuration file for the tag selection. Tag processing is (still) hard-coded, so you have to hack a bit of code to achieve what you want.

The main tag filtering and categorizing happens in osm2pgsql/output-gazetteer.cpp. In particular, you should have a look at the function place_tag_processor::process_tags(). This function is called for each OSM object and goes through its list of tags. You can simply comment out all the tags you are not interested in.

That's great, thank you! So the two settings files are to be ignored, right?

Yes, the files can be ignored. phrase_settings.php is used only when importing special phrases from the Wiki and partitionedtags.def isn't used at all anymore.
