7fcbe13669 move get_addressdata() implementation to Python 
The pgsql function get_addressdata() does a lookup of a lot of data
that is already available in Python.

fd26310d6a rerank results by query 
The algorithm is similar to the PHP reranking and uses the terms from
the display name to check against the query terms. However instead of
exact matching it uses a per-word-edit-distance, so that it is less
strict when it comes to mismatching accents or other one letter
differences.

Country names get a higher penalty because they don't receive a
penalty during token matching right now.

This will work badly with the legacy tokenizer. Given that it is
marked for removal, it is simply not worth optimising for it.

c284df2dc9 restrict range for interpolated housenumbers 
Interpolations are only supported up to 2^32 by the database.
Limit to 8 digits, which is still more than should be needed.

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.

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.

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.
