allow sorting by housenumbers for rare street names

Usually we don't narrow down search results by house number when
only a street name is given because there may be a lot of rows
to cross check when the street name is very frequent. However,
when it is known to be rare, the housenumber check may be done
anyway.

Fixes #2238.
