Subject [jira] [Commented] (LUCENE-6759) Integrate lat/long BKD and spatial 3d, part 2
Date Sat, 29 Aug 2015 10:18:46 GMT


Michael McCandless commented on LUCENE-6759:

OK I committed a new test case, {{testGeo3DRelations}}.  It tries to do what BKD does (splitting
the containing bbox to smaller and smaller cells, checking relations), but w/o actually creating
a BKD tree.  It should also be much more easily debugged: from a failing doc, if you run w/
{{-Dtests.verbose=true}}, you can trace back to see why that doc was rejected or accepted.
 You can trace each cell back with it's parent cell ID.

It could very well have its own bugs!!  It's a bit hairy.

It's current failing, e.g.:

When I run with verbose, it seems like we are getting an incorrect {{GeoArea.DISJOINT}} at
one point, causing this doc to be dropped.
