Yeah, a SpanAndQuery could easily be a SpanNearQuery if a huge distance
was allowed. I do wonder how the scoring might be different based on the
distance of the match though...

Isn't a SpanAndQuery the same as a SpanNearQuery? Perhaps

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
