-----------------------------------
Summary: don't invoke full haversin for
LatLonPoint.newDistanceQuery
Key: LUCENE-7215
URL: https://issues.apache.org/jira/browse/LUCENE-7215
Project: Lucene - Core
Issue Type: Improvement
Reporter: Robert Muir
For tree traversals and edge cases we still sometimes invoke full haversin
(with asin() call and everything). this is not necessary: we just need to
compute the exact sort key needed for comparisons.
While not a huge optimization, its obviously less work and keeps the overhead
of the BKD traversal as low as possible. And it removes the slow asin call from
any hot path (its already done for sorting too), with its large tables and so
on.
