Michael McCandless commented on LUCENE-7147:
--------------------------------------------
Wow, this is a big speedup for {{LatLonPoint.newDistanceQuery}} on the 6.1 M
point London UK benchmark: trunk is 12.3 sec for 225 queries, and this patch
brings it down to 7.7 sec!
{{GeoPointDistanceQuery}} gets a small speedup, from 16.2 sec to 15.3 sec ...
not sure why it's less.
And the total hit counts of all 4 runs are (thank God!) identical: 382,961,953

> When doing geo distance queries, it is important to avoid traversing subtrees
> which do not contain any relevant points. We currently have checks which
> compare the bbox of the query to the bounds of the subtree. However, it is
> possible for a subtree to overlap the bbox, but still not intersect the
> query. This issue is to improve that check to avoid unnecessary traversals.
