> RecursivePrefixTreeFilter has some bugs that can occur when searching indexed
> shapes. One bug is an unpositioned termsEnum. It through an exception in
> testing; I'm not sure what its effects would be in production. The other
> couple bugs are hard to describe here but were rare to occur in extensive
> testing. The effects were probably a slim chance of matching an indexed shape
> near the query shape. And SpatialPrefixTree does not support an indexed shape
> that covers the entire globe.
> These bugs were discovered during development of tests for RPTF LUCENE-4419
> which I will submit shortly.
