33c0f249b1 avoid LookupAny with address and too many name tokens
The index for nameaddress_vector has grown so large that PostgreSQL
will resort to a sequential scan if there are too many items
in the LookupAny list.

103800a732 adjust rankings for housenumber-only searches
A normal address search with housenumber will use name rankings for
the street name. This is slightly different than weighing for
address parts. Use the same ranking for the first part of the
address for housenumber-only searches to make sure that penalties
remain comparable.

f9ba7a465a always add a penalty for name + address search fallback
If there already was a search by full names, the search is likely
a repeatition that yields the same results, only running slower.

dcdda314e2 further tweak search containing very frequent tokens
Excluding non-rare full names is not really possible because it makes
addresses with street names like 'main st' unsearchable. This tries to
leav all names in but refrain from ordering results by accuracy
when too many results are expected. This means that the DB will simply
get the first n results without any particular order.

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.

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.

8366e4ca83 penalize search with frequent partials
Avoid search against frequent partials if we have already looked for
the full name equivalents.

283db76e45 avoid splitting of first token when a housenumber is present

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.
