> Key: LUCENE-9584
> URL: https://issues.apache.org/jira/browse/LUCENE-9584
> Project: Lucene - Core
> Issue Type: Improvement
> Components: core/search
> Affects Versions: 7.7.3, 8.6.3
> Reporter: hackerwin7
> Priority: Major
> Labels: performance
> Attachments: LUCENE-7.7.0-PointInSetQuery_terminate_early.patch
>
>
> Today, in a point in set query after BKD intersect we get a DocIdSetBuilder
> result, if result's iterator have no docs, then the PointInSetQuery still
> create ConstantScoreScorer with an empty DocIdSetIterator.
> In a Boolean Query, such as query = subQuery1 AND subQuery2 AND subQuery3
> .... subQueryN
> if subQuery1 is a PointInSetQuery and get a empty result iterator, and
> subsequent subQuery2 ~ subQueryN would still evaluate to call build scorer,
> this is an unnecessary cost for this query.
