cab2a74740 do not use index when searching in large areas 
This concerns viewboxes as well as radius search.

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.

The search info is in a subsearch and was therefore not taken into
account.

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.

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.

8fc3dd9457 fix query over classtype tables 
The case statement prevented the index on the classtype tables
from being used. Move the case statement inside the geometry
function instead.

8366e4ca83 penalize search with frequent partials

the full name equivalents.

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.

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

d0a1e8e311 tweak postcode search 
Give a preference to left-right reading, i.e <postcode>,<address>
prefers a postcode search while <address>,<postcode> rather does
an address search.

Also exclude non-addressables, countries and state from results when a
postcode is contained in the query.

dcfb228c9a add API functions for search functions 
Search is now split into three functions: for free-text search,
for structured search and for search by category. Note that the
free-text search does not have as many hidden features like
coordinate search. Use the search parameters for that.
