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. -- 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
