I'm trying to create a fairly complex SpanQuery from a binary parse tree. I create SpanOrQueries from SpanTermQueries and combine SpanOrQueries into BooleanQueries. So far, so good. The problem is that I don't see how to create a SpanNotQuery from a BooleanQuery and a SpanTermQuery. I want the BooleanQuery to be the 'include' span and the SpanTermQuery to be the 'exclude' span. Unfortunately, the BooleanQuery cannot be cast to a SpanQuery.
I thought that SpanQuery and BooleanQuery could be freely intermixed, but this doesn't seem to be the case. It seems that what's really needed is a 'SpanAndQuery'. Is there another way to build this type of query? Thanks, Peter
