Assignee: Tomas Eduardo Fernandez Lobbe
> BMW algorithm isn't used when scores are requested

>
> Key: SOLR-14554
> URL: https://issues.apache.org/jira/browse/SOLR-14554
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Affects Versions: master (9.0), 8.6
> Reporter: Tomas Eduardo Fernandez Lobbe
> Assignee: Tomas Eduardo Fernandez Lobbe
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> This is because, when scores are requested, we use MultiCollector, and it
> will end up using a scorer that explicitly skips delegating calls to set the
> minimum competitive score:
> {code:java}
> @Override
> public void setScorer(Scorable scorer) throws IOException {
> if (cacheScores) {
> scorer = new ScoreCachingWrappingScorer(scorer);
> }
> scorer = new FilterScorable(scorer) {
> @Override
> public void setMinCompetitiveScore(float minScore) throws IOException
> {
> // Ignore calls to setMinCompetitiveScore so that if we wrap two
> // collectors and one of them wants to skip low-scoring hits, then
> // the other collector still sees all hits. We could try to
> reconcile
> // min scores and take the maximum min score across collectors, but
> // this is very unlikely to be helpful in practice.
> }
> };
> for (int i = 0; i < numCollectors; ++i) {
> final LeafCollector c = collectors[i];
> c.setScorer(scorer);
> }
> }
> {code}
