Robert Muir updated LUCENE-7124:
--------------------------------
Attachment: LUCENE-7124.patch
Here is a stab at a patch. It reduces tables from ~352KB to ~64KB, and in my
measurements is ~ 20% faster.
> SloppyMath is too accurate

> Followup from LUCENE-7123:
> Latitude/longitude values are encoded by GeoPointField/LatLonPoint with 1E-6
> or 1E-7 error.
> However, the sloppy distance formula is far too accurate to the actual
> (10nm), making it slower and relying on large tables. We should only do as
> good as we need, and especially try to reduce the huge tables.
