jpountz opened a new pull request, #14970:
URL: https://github.com/apache/lucene/pull/14970
PRs #14906 and #14896 improved the efficiency of filtering by score. This PR
tries to get some extra speedup by:
- Skipping filtering by score when applying a non-essential clause that
doesn't have matches over the range of doc IDs being scored.
- Filtering on float[] scores rather than double[] scores whenever
applicable so that vectorization can work on 2x more lanes at once.
- Filtering by score using `VectorUtil#filterByScore` instead of relying on
the collector to do it.
