David Smiley commented on LUCENE-4585:
--------------------------------------
I'll commit this tomorrow if there are no objections.
For those of you that didn't look at the patch, note that it adds an entry up
in the API compatibility section:
{quote}
* LUCENE-4585: Spatial PrefixTree based Strategies (either TermQuery or
RecursivePrefix based) MAY want to re-index if used for point data. If a
re-index is not done, then an indexed point is ~1/2 the smallest grid cell
larger and as such is slightly more likely to match a query shape.
(David Smiley)

Strictly speaking this is not an API change but there wasn't a upgrade section.
This note I added is also quite minor (in fact the behavior of a point
matching its entire grid cell might be desirable) so arguably I could simply
not mention it; but I'm err'ing on the side of full disclosure.

> 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.
