Actually, I was thinking of writing something along the lines of
Span*BoundaryQuery where it would be more explicit than what was
described below. You could say SpanSentence and say you want the terms
to occur w/in two sentences. Do you guys think it is worthwhile to
codify what is discussed below into a few convenience Span queries, or
maybe we should just write it up better and put on the wiki or something...
Any preference?

I haven't tried it myself, but my reading of SpanQueries leads me to
believe you could accomplish what you want (and what Grant describes) by
inserting special Terms to denote
formula/sentance/paragraph/section/chapter boundaries, and then use
SpanNearQueries with a high slop in conjunction with a
SpanNotQuery using a SpanTermQuery for the boundary you don't want to
cross.
I have not tried this either, but it was one of the use cases when
designing span queries. So it should work.
