Paul Elschot commented on LUCENE-1252: -------------------------------------- There is no patch for now. HitCollectors should not be affected by this, as they would only be involved when a real match is found, and that, when position info is needed, necessarily involves the positions. Extending this with a cheap score brings another issue: should a cheap score be given for a document that might match, but in the end does not really match when positions are used? At the moment, I don't think so: score values are normally cheap to compute, but accessing positions is not cheap. > 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: java-dev-unsubscr...@lucene.apache.org For additional commands, e-mail: java-dev-h...@lucene.apache.org
