endless loop when querying using BooleanQuery. ---------------------------------------------- Key: LUCENE-700 URL: http: //issues.apache.org/jira/browse/LUCENE-700 Project: Lucene - Java Issue Type: Bug Components: Search Reporter: kaineci the extreme case is: when querying term1, term2, term3 and current docid of inverted lists of term1, term2, term3 are 0, i (larger than 0), BucketTable.SIZE, what could happen in search???However this case should occur with low possibility. BucketTable table = new BucketTable(); Random random = new Random(); int tmpValue = random.nextInt(Integer.MAX_VALUE); table.newCollector().collect(0, 0); table.newCollector().collect(tmpValue, tmpValue); table.newCollector().collect(2048, 2048); Bucket bucket = table.first; while(bucket != null) { bucket = bucket.next; num++; } -- 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.atl assian.com/software/jira ------------------------------------------------------------ --------- To unsubscribe, e-mail: java-dev-unsubscribelucene.apache.org For additional commands, e-mail: java-dev-helplucene.apache.org
