The two changes (in DisjunctionSumScorerPatch5.txt and in the posted SpanScorer) are different in that for DisjunctionSumScorer the test is against the current doc of the scorer and in SpanScorer the test is against the current doc of the subscorer. So I think in DisjunctionSumScorer the test may not be needed, but in SpanScorer it should be there. However, I don't have a test case showing the out of bounds problem, so I'd like to know whether this problem persists with the posted SpanScorer. > [PATCH] BooleanScorer2 ArrayIndexOutOfBoundsException + alternative NearSpans > ----------------------------------------------------------------------------- > > Key: LUCENE-413 > URL: http://issues.apache.org/jira/browse/LUCENE-413 > Project: Lucene - Java > Type: Bug > Components: Search > Versions: CVS Nightly - Specify date in submission > Environment: Operating System: other > Platform: Other > Reporter: paul.elschot > Assignee: Lucene Developers > Attachments: DisjunctionSumScorerPatch3.txt, DisjunctionSumScorerPatch4.txt, > DisjunctionSumScorerPatch5.txt, DisjunctionSumScorerTestPatch1.txt, > NearSpansOrdered.java, NearSpansOrderedBugHuntPatch1.txt, > NearSpansUnordered.java, SpanNearQueryPatch1.txt, SpanScorer.java, > SpanScorerTestPatch1.txt, TestSpansAdvanced.java, TestSpansAdvanced2.java > > From Erik's post at java-dev: > > > [java] Caused by: java.lang.ArrayIndexOutOfBoundsException: 4 > > [java] at org.apache.lucene.search.BooleanScorer2 > > $Coordinator.coordFactor(BooleanScorer2.java:54) > > [java] at org.apache.lucene.search.BooleanScorer2.score > > (BooleanScorer2.java:292) > ... > > and my answer: > > Probably nrMatchers is increased too often in score() by calling score() > more than once. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
