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.

fed46240d5 disallow category tokens in the middle of a query string 
This already worked for left-to-right readings and now is also
implemented for right-to-left reading. A qualifier must always be
before or after the name.

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.

10a5424a71 do not run near queries on qualifier words 
There is too much potential for confusion (e.g. 'Rio Grande' read
as 'river near Grande') fir too little gain. Use near phrases
instead.

Use JSON arrays which can have mixed types and therefore have
a more logical structure than separate arrays. Avoid JSON dicts
because of their verboseness.

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.
