> This patch addresses a TODO in QueryRescorer: We should not sort the full array of the results returned from rescoring, but rather only topN, when topN is less than total hits.
>  
> Made this optimization with some suggestions from [~jpountz] and [~jimczi], this is my first lucene patch submission.
