             Summary: Use exact distance between point and bounding rectangle in FloatPointNearestNeighbor
                 Key: LUCENE-8976
                 URL: https://issues.apache.org/jira/browse/LUCENE-8976
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Ignacio Vera


Calculating minimum distance between a point and a bounding rectangle can be computed quite efficiently. This allows the FloatPointNearestNeighbor algorithm to discard inner nodes based on that calculation.
