LUCENE-9346: Support minimumNumberShouldMatch in WANDScorer (#2141)
Co-authored-by: Adrien Grand <jp...@gmail.com>
> WANDScorer should support minimumNumberShouldMatch
> --------------------------------------------------
>
> Key: LUCENE-9346
> URL: https://issues.apache.org/jira/browse/LUCENE-9346
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Adrien Grand
> Priority: Minor
> Time Spent: 3.5h
> Remaining Estimate: 0h
>
> Currently we deoptimize when a minimumNumberShouldMatch is provided and fall back to a scorer that doesn't dynamically prune hits based on scores.
> Given how WANDScorer and MinShouldMatchSumScorer are similar I wonder if we could remove MinShouldSumScorer once WANDScorer supports minimumNumberShould match. Then any improvements we bring to WANDScorer like two-phase support (LUCENE-8806) would automatically cover more queries.
