283db76e45 avoid splitting of first token when a housenumber is present 
This only covers the case of <poi name> <street name> <housenumber>
which is exceedingly rare.

8a36ed4f6f increase threshold for full name searches

d0f45155c8 fix search for housenumber names 
The search still included a lookup of housenumbers in children which is
wrong.

75139961a3 use constant expressions to select partial indexes in reverse 
When expressions are generated with SQLAlchemy, any constants are
replaced with bind parameters. The bind parameters become parameters of
prepared statements. The result is that the query planner tends to
oversee that the partial indexes can be used.

e67355ab0e make get_addressdata calls cachable 
VALUEs() is not a cachable construct in SQLAlchemy, so use arrays
instead. Also add a special case for single results, the usual result
for reverse queries.
