Adrien Grand commented on LUCENE-8439:
--------------------------------------
Pretty cool. I guess it works well because scores on title dominate the overall
score?
Should we factor out a DocIdSetIterator implementation similar to ImpactsDISI
but that would take a Scorer rather than an ImpactsSource to reuse in
ReqOptSumScorer, DisjunctionMaxScorer and probably other scorers
(ConstantScoreScorer and CoveringScorer come to mind).
Maybe we should also replace {{boolean needsScores}} with {{ScoreMode
scoreMode}} so that we would only wrap the approximation when top scores are
needed rather than all scores?
> DisjunctionMaxScorer should leverage sub scorers' per-block max scores
