Yup, Lance is right.  But it won't always work if you have multi-valued data
since it wouldn't match a document that had a point both in the ring and the
hole.

Another approach that internally works faster and addresses the multi-value
case is to implement a custom Spatial4j Shape.  In this case, you could
create a special aggregate Shape that basically accepts one shape and
excludes the other, in its custom relate() method.  It's like a subtracting
shape.  This is generically useful and on my list of things to do but I
haven't had the need.  The other step would be parsing it somehow, so you
might do that by extending the existing spatial 4 field type.
