Uwe Schindler updated LUCENE-504: --------------------------------- Attachment: LUCENE-504.patch Here a patch, that fixes FuzzyQuery. It uses j.u.PQ and has a small optimization to not add ScoreTerms, that would never be seen in the first maxClauseCount terms (tracking a bottom value). It also adds an testcase, where the maxClauseCount is lowerd downto 2 and the FuzzyQuery would hit 3 terms, so one too much. This tests the algorithm to not add this entry to the PQ. Nadav: The solution you propsed for limiting the number of entries in the PQ does not work, as poll() removes the head element of the queue, not the bottom that falls out. There is no way to remove the bottom value in Java's PQ easily. So we should j.u.PQ only for this issue. > FuzzyQuery produces a "java.lang.NegativeArraySizeException" in > PriorityQueue.initialize if I use Integer.MAX_VALUE as > BooleanQuery.MaxClauseCount > -------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: LUCENE-504 > URL: https://issues.apache.org/jira/browse/LUCENE-504 > Project: Lucene - Java > Issue Type: Bug > Components: Search > Affects Versions: 1.9 > Reporter: Joerg Henss > Priority: Minor > Attachments: BooleanQuery.java.diff, fuzzyquery.patch, > LUCENE-504.patch, LUCENE-504.patch, PriorityQueue.java.diff, > TestFuzzyQueryError.java > > > PriorityQueue creates an "java.lang.NegativeArraySizeException" when > initialized with Integer.MAX_VALUE, because Integer overflows.
