David Smiley commented on LUCENE-4644:
--------------------------------------
I confirm your interpretation of "WITHIN" semantics being the "all within" that
I defined above, and so that should be the default.
My "some within" definition is not synonymous with "Intersects", just to be
clear. It is a subset of "Intersects" where the boundary of the indexed shape
does not cross the query shape. As such, some of the indexed shape must be
within the query shape but it cannot cross over directly outside of the query
shape. It can match more documents than the standard WITHIN will match, for
those cases where the indexed shape is comprised of multiple disjoint pieces.
