> 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)
