Paul Elschot commented on LUCENE-1252: -------------------------------------- LUCENE-2410 has solved this partially for PhraseQuery/PhraseScorer by computing only the first matching phrase to determine a possible match, and by delaying the computation of the remaining matches until score() is called. > Avoid using positions when not all required terms are present > ------------------------------------------------------------- > > Key: LUCENE-1252 > URL: https://issues.apache.org/jira/browse/LUCENE-1252 > Project: Lucene - Java > Issue Type: Wish > Components: Search > Reporter: Paul Elschot > Priority: Minor > > In the Scorers of queries with (lots of) Phrases and/or (nested) Spans, > currently next() and skipTo() will use position information even when other > parts of the query cannot match because some required terms are not present. > This could be avoided by adding some methods to Scorer that relax the > postcondition of next() and skipTo() to something like "all required terms > are present, but no position info was checked yet", and implementing these > methods for Scorers that do conjunctions: BooleanScorer, PhraseScorer, and > SpanScorer/NearSpans. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
