Simon Willnauer commented on LUCENE-4236: ----------------------------------------- cool nice little optimization! looks good to me while you could add that minShouldMatch only applies to optional scorers so nobody needs to hunt that down again > clean up booleanquery conjunction optimizations a bit > ----------------------------------------------------- > > Key: LUCENE-4236 > URL: https://issues.apache.org/jira/browse/LUCENE-4236 > Project: Lucene - Java > Issue Type: Improvement > Reporter: Robert Muir > Fix For: 4.0, 5.0 > > Attachments: LUCENE-4236.patch, LUCENE-4236.patch > > > After LUCENE-3505, I want to do a slight cleanup: > * compute the term conjunctions optimization in scorer(), so its applied even > if we have optional and prohibited clauses that dont exist in the segment > (e.g. return null) > * use the term conjunctions optimization when optional.size() == > minShouldMatch, as that means they are all mandatory, too. > * don't return booleanscorer1 when optional.size() == minShouldMatch, because > it means we have required clauses and in general BS2 should do a much better > job (e.g. use advance). I have no idea if this is the problem in SOLR-3636. -- This message is automatically generated by JIRA.
