ASF subversion and git services commented on LUCENE-9541: --------------------------------------------------------- Commit 5f34acfdb59f58987e0f69e8876e190b5e91dd3a in lucene-solr's branch refs/heads/master from Mayya Sharipova [ https://gitbox.apache.org/repos/asf?p=lucene-solr.git;h=5f34acf ] LUCENE-9541 ConjunctionDISI sub-iterators check (#1937) * LUCENE-9541 ConjunctionDISI sub-iterators check Ensure sub-iterators of a conjunction iterator are on the same doc. > Ensure sub-iterators of ConjunctionDISI are on the same document > ---------------------------------------------------------------- > > Key: LUCENE-9541 > URL: https://issues.apache.org/jira/browse/LUCENE-9541 > Project: Lucene - Core > Issue Type: Bug > Reporter: Mayya Sharipova > Priority: Minor > Time Spent: 1h 20m > Remaining Estimate: 0h > > Not completely sure if this is a bug. > BitSetConjuctionDISI advances based on its lead – DocIdSetIterator iterator, > and doesn't consider that its another component – BitSetIterator may have > already advanced passed a certain doc. This may result in duplicate documents. > For example if BitSetConjuctionDISI _disi_ is composed of DocIdSetIterator > _a_ of docs [0,1] and BitSetIterator _b_ of docs [0,1]. Doing `b.nextDoc()` > we are collecting doc0, doing `disi.nextDoc` we again collecting the same > doc0. > It seems that other conjunction iterators don't have this behaviour, if we > are advancing any of their component pass a certain document, the whole > conjunction iterator will also be advanced pass this document. > > This behaviour was exposed in this > [PR|https://github.com/apache/lucene-solr/pull/1903]. > -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
