Subject: allow coordinates in query only with name or classtype

allow coordinates in query only with name or classtype

Coordinates with country or housenumber only do not make much
sense. Currently these combination result in queries that
require a sequential scan of search_name and normally time
out before yielding any results.

fixes #462
