> 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.
> *Note*
> This problem occurs in distributed search (SolrCloud) or the fl=score parameter specified.
