Adrien Grand commented on LUCENE-9620: -------------------------------------- Sorry I wasn't clear: I would like to keep {{IndexSearcher#count}} but I would still like to add {{Weight#count}} so that Weight objects can optimize counting themselves instead of resorting to {{instanceof}} checks in {{IndexSearcher#count}}. > Add Weight#count(LeafReaderContext) > ----------------------------------- > > Key: LUCENE-9620 > URL: https://issues.apache.org/jira/browse/LUCENE-9620 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Adrien Grand > Priority: Minor > > We have IndexSearcher#count today, which tries to optimize counting for > TermQuery and MatchAllDocsQuery, and falls back to BulkScorer + > TotalHitCountCollector otherwise. > I'm considering moving this to Weight instead, where it'd be a better place > to add counting optimizations for other queries, e.g. pure disjunctions over > single-valued fields or range queries on points. The default implementation > could use a BulkScorer+TotalHitCountCollector like IndexSearcher#count does > today. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
