Dallan Quass commented on LUCENE-413:
-------------------------------------

Sorry for cluttering up the comments here.  I wanted to add that the part o=
f the query exhibiting the error in the second case is a boolean query with=
 three SpanTermQuery clauses, all "Occur.SHOULD."  If I change the SpanTerm=
Query clauses to just TermQuery clauses, the problem goes away.
