Hello,

We have installed a fresh instance of Nominatim using docker by following the installation steps from https://nominatim.org/release-docs/develop/admin/Installation/ . I doubled checked multiple times for everything to be up-to-date. TIGER data is also up to date.

Unfortunately, we have observed some differences between what our server returns and what the public Nominatim platform shows by using the same search parameters.

Here are the search parameters: street=520+Madison+Avenue&city=new+york&state=ny&postalcode=10022

Local url: http://142.132.128.187:8080/search.php?street=520+Madison+Avenue&city=new+york&state=ny&postalcode=10022&format=jsonv2 Public url: https://nominatim.openstreetmap.org/search.php?street=520+Madison+Avenue&city=new+york&state=ny&postalcode=10022&format=jsonv2

Could you please help us identify what is the root cause of this behavior?

Many thanks!

You are not running the same software version of Nominatim and you are using different data. Differences are to be expected.

The public servers at https://nominatim.openstreetmap.org are on a rolling release of the latest development version of Nominatim and are updated with minutely diffs. It is not possible to set up a local instance that is in exactly the same state.

We understand that may be a slight difference between a local environment and the public servers. The issue in hand is that the difference is way too obvious, given the large difference in the number of responses obtained using both versions.

As we stated earlier we are running with the latest data and software version, here are some information on that: - PBF_URL: https://ftp5.gwdg.de/pub/misc/openstreetmap/planet.openstreetmap.org/pbf/planet-latest.osm.pbf - REPLICATION_URL: https://ftp5.gwdg.de/pub/misc/openstreetmap/planet.openstreetmap.org/replication/day/ - PostgreSQL 12.9 (Ubuntu 12.9-0ubuntu0.20.04.1) - ENV NOMINATIM_VERSION 4.0.1

We also went ahead and installed all the auxiliary data sources according to https://nominatim.org/release-docs/latest/develop/data-sources/ .

Is there anything left to be installed/configured to be somewhat inline with the public servers ?

You can try reimporting with NOMINATIM_TOKENIZER=icu. It may or may not help. Depends on what your exact issue with the search results is. As it stands, the result on your server seems to be the more correct one.

Thank you for your answer Ionvia, we have already imported with "ICU" tokenizer.

Is there any difference in the search logic between a local instance and the public servers ?
