Robert Muir commented on LUCENE-8928:
-------------------------------------
I guess I'm saying, I don't see any evidence of speedups for 2 dimensions
above. For > 2 dimensions, the indexing cost is worth the increased search
performance, but for 2 dimensions it isn't the right tradeoff.
> BKDWriter could make splitting decisions based on the actual range of values

> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Adrien Grand
> Priority: Minor
>
> Currently BKDWriter assumes that splitting on one dimension has no effect on
> values in other dimensions. While this may be ok for geo points, this is
> usually not true for ranges (or geo shapes, which are ranges too). Maybe we
> could get better indexing by re-computing the range of values on each
> dimension before making the choice of the split dimension?
