> 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.
