Subject [jira] [Commented] (LUCENE-6532) Add GeoPointDistanceQuery for GeoPointField type
Date Thu, 11 Jun 2015 21:30:00 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-6532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14582539#comment-14582539

Michael McCandless commented on LUCENE-6532:
--------------------------------------------

Thanks [~nknize] this is some heavy math :)

I wonder if we should provide a Haversine impl (default?) that's faster but a bit off (22
meters from your comment)?

Do you have a simple benchmark somewhere (you mentioned a 60% speedup)?

In the 2nd patch, do you skip the polygon approximation entirely?  It's curious that made
things so much faster; it seems like that should have avoided a large number of per-hit distance
calculations.
