95d1048789 take token_assignment penalty into account 
Also computes the expected count differently when addresses are
involved. Address token counts do not bare a direct relation to
real counts.

3d0bc85b4d improve penalty for token-split words 
The rematch penalty for partial words created by the transliteration
need to take into account that they are rematched against the full word.
That means that missing beginning and end should not get a significant
penalty.

78648f1faf remove lookup by address only 
There are too many lookups where the address is very frequent,
even when many address parts are present.

8d9b5e4775 allow oversized viewboxes again 
This seems to be a rather regular thing when unconditionally sending
the current view and being zoomed out.

afdbdb02a1 do not lookup by address vector when only few tokens are available 
Names of countries and states are exceedingly rare in the word count
but are very frequent in the address. A short name has the danger
of producing too many results.

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.
