Comment (by lonvia):

 I've set up a test instance with this patch at
 http://osm.lonvia.de/nominatim/
 (CZ, SK only and no Wikipedia importance, so search results may be ordered
 differently)

 It looks good as far as I can see, maybe a few locals could look over it
 and confirm that it does not result in regressions or weird behaviour with
 search. Please keep in mind that this patch does not resolve the issue
 with addresses without a street name. They still won't be found.

 I have a mild reservation against overwriting addr:housenumber but
 according to taginfo addr:conscriptionnumber is used in CZ/SK only and the
 few addr:streetnumber tags outside of these countries seem to be mostly
 tagging errors. So, if it goes with local conventions, then so be it.
 twain, any thoughts?

 One final thing you should be aware of: this patch has not only an
 influence on search but also on address lookup. When looking up
 coordinates, the addresses will also always be returned with house numbers
 in conscriptionnumber/streetnumber format.
