Michael McCandless commented on LUCENE-7215: -------------------------------------------- +1, cool > 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 > Attachments: LUCENE-7215.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
