David Smiley commented on LUCENE-4644:
--------------------------------------
Come to think of it, I can't even do a proper fast "some within" as I earlier
hoped because the code wouldn't be able to (easily) detect when one disjoint
part is within the query yet another spans the edge.
Any way, I think the epiphany I had above on how to implement a fast (all)
WITHIN, using an indexed center points cache, should work pretty well. I'll
proceed with that. There could be an option to provide a hint that the center
point cache isn't needed, like when you simply index a single point per
document, for example.
