I am seeing this issue as well with the exact same stack trace using spanQueries. Does anyone know if this has been fixed for versions after 1.9.1?
Thanks Gary -----Original Message----- From: Erick Erickson [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 23, 2006 07:23 AM To: java-user@lucene.apache.org Subject: An arguable bug in Lucene 1.9.1 I'm constructing a BooleanQuery across several fields with SpanNearQuerys. In the degenerate case of spanning *one* term, AND adding a non-span clause, I get an exception thrown. Of course you can argue that a span query over one term is silly and shouldn't be done, but I thought I'd mention this. I'm content with whatever y'all decide. Here's the results of a BooleanQuery.toString: +(spanNear([person:john], 20, false) spanNear([text:john], 5, false)) +groupid:14075 This results in the following stack trace: ava.lang.ArrayIndexOutOfBoundsException: 4 at org.apache.lucene.search.BooleanScorer2$Coordinator.coordFactor( BooleanScorer2.java:54) at org.apache.lucene.search.BooleanScorer2.score(BooleanScorer2.java :328) at org.apache.lucene.search.ConjunctionScorer.score( ConjunctionScorer.java:82) at org.apache.lucene.search.BooleanScorer2$2.score(BooleanScorer2.java :186) at org.apache.lucene.search.BooleanScorer2.score(BooleanScorer2.java :327) at org.apache.lucene.search.BooleanScorer2.score(BooleanScorer2.java :291) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:132) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:110) at org.apache.lucene.search.Searcher.search(Searcher.java:76) ****my code here If I take off the end clause, or have more than one string in the span, it works. e.g. +(spanNear([person:john], 20, false) spanNear([text:john], 5, false)) works, as does: +(spanNear([person:john, person:johnson], 20, false) +spanNear([text:john, text:johnson], 5, false)) +groupid:14075 Of course I can (and will) intercept the creation of the span queries when there is only one term and use TermQuery instead. I suspect that this is better practice anyway. I'll be happy to enter this in bugs database if you think I should.
