-------------------------------
Summary: Score returned in search request is original score and
not reranked score
Key: LUCENE-9542
URL: https://issues.apache.org/jira/browse/LUCENE-9542
Project: Lucene - Core
Issue Type: Bug
Affects Versions: 8.0
Reporter: Krishan
Score returned in search request is original score and not reranked score post
the changes in https://issues.apache.org/jira/browse/LUCENE-8412
Specifically -
if (cmd.getSort() != null && query instanceof RankQuery == false &&
(cmd.getFlags() & GET_SCORES) != 0) {
TopFieldCollector.populateScores(topDocs.scoreDocs, this, query);
}
in SolrIndexSearcher.java recomputes the score but outputs only the original
score and not the reranked score.
The issue is cmd.getQuery() is a type of RankQuery but the "query" variable is
a boolean query and probably replacing query with cmd.getQuery() should be the
right fix for this so that the score is not overriden for rerank queries
