jtibshirani opened a new pull request #832: LUCENE-8952: Use a sort key instead of true distance in NearestNeighbors.
URL: https://github.com/apache/lucene-solr/pull/832
 
 
   This commit addresses a TODO in NearestNeighbors around switching to
   `SloppyMath.haversinSortKey`. When comparing candidate hits, we now only compute
   a distance sort key. The sort key is converted to a true distance only when returning
   the final set of `FieldDocs` and when calculating the bbox for the current search area.
