Edinburgh and Buenos Aires low ranked
Closed this issue · 3 comments
It is very hard to find "Edinburgh" in Scotland and "Buenos Aires". It seems something is wrong with the ranking on these - as other hamlets and villages appears in front of these capitals.
Maybe related to:
OSMNames/OSMNames#41
Is there a problem with OSMNames data on these two examples @MartinMikita ?
Upps.
Phrase "Zurich" will not found the city either. See:

only
http://osmnames.klokantech.com/#q=zurich%2C%20switzerland
Phrase "Edinburgh" will not found the city in Scotland.
Only http://osmnames.klokantech.com/#q=Edinburgh%20scotland will.
Phrase "Paris" has the same issue!
THIS IS URGENT @MartinMikita.
I found a problem - overflow of weight value.

There is no enforced limit on the maximum weight value at the moment. However, beware that if you set it too high you can start hitting 32-bit wraparound issues. For instance, if you set a weight of 10,000,000 and search in extended mode, then maximum possible weight will be equal to 10 million (your weight) by 1 thousand (internal BM25 scaling factor, see Section 5.4, “Search results ranking”) by 1 or more (phrase proximity rank). The result is at least 10 billion that does not fit in 32 bits and will be wrapped around, producing unexpected results.
