House numbers need special handling because they may appear after the street term. That means we canot just use them as the main name for searches where the address has its own search term entries. Doing this right now, we are able to find '40, Main St, Town' but not 'Main St 40, Town'. This switches to using the housenumber token as the name term instead. House number tokens can get special handling when building the search query that covers the case where they come after the street. The main disadvantage is that this once more increases the numbers of possible search interpretation of which we have already too many. no penalty for housenumber searches
Nominatim
Nominatim (from the Latin, 'by name') is a tool to search OpenStreetMap data by name and address (geocoding) and to generate synthetic addresses of OSM points (reverse geocoding). An instance with up-to-date data can be found at https://nominatim.openstreetmap.org. Nominatim is also used as one of the sources for the Search box on the OpenStreetMap home page.

Installation
Nominatim is a complex piece of software and runs in a complex environment. Installing and running Nominatim is something for experienced system administrators only who can do some trouble-shooting themselves. We are sorry, but we can not provide installation support. We are all doing this in our free time and there is just so much of that time to go around. Do not open issues in our bug tracker if you need help. You can ask questions on the mailing list (see below) or on help.openstreetmap.org.
The latest stable release can be downloaded from https://nominatim.org. There you can also find installation instructions for the release, as well as an extensive Troubleshooting/FAQ section.
Detailed installation instructions for the development version can be found at nominatim.org as well.
