b2afe3ce3e when a country is in the results, restrict further searches to places 
A country search result usually comes with a very high importance.
As a result only other very well known places will show up together
with country results and that means only places with lower address
ranks. Name searches for country names tend to yield a lot of POI
results because the country name is part of the name
(think "embassy of Sweden"). By excluding POIs from further searches,
the search is sped up quite a bit.

615b166c68 clean up ST_DWithin and intersects() functions 
A non-index version of ST_DWithin is not necessary. ST_Distance
can be used for that purpose. Index use for intersects can be
covered with a simple parameter.

b2319e52ff correctly exclude streets with housenumber searches 
Street result are not subject to the full filtering in the SQL
query, so recheck.

a8b023e57e restrict base results in near search by rank 
This avoids in particular that roads or POIs are used as base
for the near search when a place result is present.

7fcbe13669 move get_addressdata() implementation to Python

that is already available in Python.

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.

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.
