[ http://issues.apache.org/jira/browse/LUCENE-504?page=comments#action_12415800 ]
Doron Cohen commented on LUCENE-504: ------------------------------------ LuceneFAQ item "Why am I getting a TooManyClauses exception?" suggests: "use BooleanQuery.setMaxClauseCount(Integer.MAX_VALUE)". This would cause PriorityQueue to create an array of size maxint: - SUN JRE throws an out-of-memory error. - IBM JRE throws a "too large allocation" runtime error. Seems that at least two fixes are required: + BooleanQuery - hard limit on value of maxClauseCount + PriorityQueue - hard limit on size of queue, since it is stored in memory. The attached would set 1,000,000 hard limit - defined in PriorityQueu - I think the most intensive use of priority queue is for docs/hits during search, and 1M docs seems sufficient, unless there are uses that I am not aware of. > FuzzyQuery produces a "java.lang.NegativeArraySizeException" in > PriorityQueue.initialize if I use Integer.MAX_VALUE as > BooleanQuery.MaxClauseCount > -------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: LUCENE-504 > URL: http://issues.apache.org/jira/browse/LUCENE-504 > Project: Lucene - Java > Type: Bug > Components: Search > Versions: 1.9 > Reporter: Joerg Henss > Priority: Minor > Attachments: TestFuzzyQueryError.java > > PriorityQueue creates an "java.lang.NegativeArraySizeException" when > initialized with Integer.MAX_VALUE, because Integer overflows.
