> BlendedInfixSuggester bad score calculus for certain suggestion weights
> -----------------------------------------------------------------------
>
> Key: LUCENE-8343
> URL: https://issues.apache.org/jira/browse/LUCENE-8343
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/search
> Affects Versions: 7.3.1
> Reporter: Alessandro Benedetti
> Priority: Major
> Attachments: LUCENE-8343.patch
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Currently the BlendedInfixSuggester return a (long) score to rank the suggestions.
> This score is calculated as a multiplication between :
> long *Weight* : the suggestion weight, coming from a document field, it can be any long value ( including 1, 0,.. )
> double *Coefficient* : 0<=x<=1, calculated based on the position match, earlier the better
> The resulting score is a long, which means that at the moment, any weight<10 can bring inconsistencies.
> *Edge cases*
> Weight =1
> Score = 1( if we have a match at the beginning of the suggestion) or 0 ( for any other match)
> Weight =0
> Score = 0 ( independently of the position match coefficient)
