Alan Woodward commented on LUCENE-6850: --------------------------------------- +1 Another possible optimization here is to check the number of docs in the segment, and if it's below a certain size then don't use the bulk scorer. For example, big disjunctions run against a MemoryIndex currently allocate int[2048] for each node even though there's only a single doc in there. > BooleanWeight should not use BS1 when there is a single non-null clause > ----------------------------------------------------------------------- > > Key: LUCENE-6850 > URL: https://issues.apache.org/jira/browse/LUCENE-6850 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Adrien Grand > Assignee: Adrien Grand > Priority: Minor > Attachments: LUCENE-6850.patch, LUCENE-6850.patch > > > When a disjunction has a single non-null scorer, we still use BS1 for > bulk-scoring, which first collects matches into a bit set and then calls the > collector.
