[GitHub] [lucene-solr] chlorochrule opened a new pull request #2259: SOLR-15114: WAND does not work correctly on multiple segments in Solr 8.6.3
chlorochrule opened a new pull request #2259:
URL: https://github.com/apache/lucene-solr/pull/2259
## Description
In Solr 8.6.3, minCompetitiveScore of WANDScorer resets to zero for each index segment and remain zero until maxScore is updated.
There are two causes of this problem:
- MaxScoreCollector does not set minCompetitiveScore of MinCompetitiveScoreAwareScorable newly generated for another index segment.
- MaxScoreCollector updates minCompetitiveScore only if maxScore is updated. This behavior is correct considering the purpose of MaxScoreCollector.
For details, see the attached pdf https://issues.apache.org/jira/secure/attachment/13019548/wand.pdf.
Fixed https://issues.apache.org/jira/browse/SOLR-15114
