Ignacio Vera created LUCENE-8914:
------------------------------------
Summary: Small improvement in FloatPointNearestNeighbor
Key: LUCENE-8914
URL: https://issues.apache.org/jira/browse/LUCENE-8914
Project: Lucene - Core
Issue Type: Improvement
Reporter: Ignacio Vera
Currently the logic to visit inner nodes of the BKD tree in
FloatPointNearestNeighbor is in the custom tree traversing logic instead of in
the IntersectVisitor. This approach is missing the improvement added on
LUCENE-7862 which my experiments shows that for a high number of dimensions can
give a performance improvements of around 10%.
This change proposes to move the logic for discarding inner modes to the
IntersectVisitor.
