Subject [jira] [Commented] (LUCENE-7212) Add Geo3DPoint equivalents of LatLonPointDistanceComparator and LatLonPointSortField
Date Wed, 27 Apr 2016 11:05:12 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-7212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15259973#comment-15259973

Karl Wright commented on LUCENE-7212:
-------------------------------------

[~mikemccand], the resolution is quite important for determination if in-set/out-of-set for
shapes like small circles.  However, for distance measurement/ordering, I can't see any need
to be that precise, so if the docvalues is only used for distance computation then 64 bits
should be OK.

> Geo3D has a number of distance measurements and a generic way of computing interior distance.
 It would be great to take advantage of that for queries that return results ordered by interior
distance.
