-----------------------------------
Summary: further optimize LatLonPoint.newDistanceSort
Key: LUCENE-7103
URL: https://issues.apache.org/jira/browse/LUCENE-7103
Project: Lucene - Core
Issue Type: Improvement
Reporter: Robert Muir
This comparator creates bounding boxes to avoid calling haversin(), so its no
longer a hotspot for most use cases.
But in the worst case, it could still get called many times. This could be
because the user had a massive top N value, or because the incoming data is
sorted or mostly sorted by decreasing distance, etc.
We can optimize the worst case by not invoking a full haversin, just using
something that is rank-equivalent.
