Nicholas Knize commented on LUCENE-6908:
++ Thanks [~steve_rowe] There's a geometric approximation in the within that's
a bit too lenient for BKD. These seeds have been super helpful in regression
testing a fix. Should have a patch shortly. Sorry for the noise!

Michael McCandless commented on LUCENE-6908:
Those benchmark results are nice [~nknize]! Is the source for this bench
checked in somewhere? From this, it seems like we should switch to Sinnot
Haversine? It's fastest and lowest error?
I beasted for a while and no failures!
+1 to commit! Hopefully this means we can add {{DimensionalDistanceQuery}} and
it just works!

> The {{.testGeoRelations}} method doesn't exactly test the behavior of
> GeoPoint*Query as its using the BKD split technique (instead of quad cell
> division) to divide the space on each pass. For "large" distance queries this
> can create a lot of irregular rectangles producing large radial distortion
> error when using the cartesian approximation methods provided by
> {{GeoUtils}}. This issue improves the accuracy of GeoUtils cartesian
> approximation methods on irregular rectangles without having to cut over to
> an expensive oblate geometry approach.

[jira] [Commented] (LUCENE-6908) TestGeoUtils.testGeoRelations is buggy with irregular rectangles

Michael McCandless commented on LUCENE-6908:
Hi [~nknize], I think you forgot to add {{GeoRelationUtils.java}} before making
the patch? And also, can you make the patch from higher up in the source tree?
It seems to be missing e.g. changes to {{SloppyMath.java}}.
