> Score returned in search request is original score and not reranked score post the changes in https://issues.apache.org/jira/browse/LUCENE-8412.
> Commit - [https://github.com/apache/lucene-solr/commit/55bfadbce115a825a75686fe0bfe71406bc3ee44#diff-4e354f104ed52bd7f620b0c05ae8467d]
> 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
