Karl Wright commented on LUCENE-7212:
-------------------------------------

bq. It might be worthwhile to investigate what is happening with polygons with 
geo3d though, i think something is not right there.

Something is definitely funny.  Did you try this with prebuilt queries, or 
without?  Query construction is likely to be slow, and this is known -- it's an 
O(N^2) algorithm in places.

[~mikemccand]: any idea why these numbers would be so different from the ones 
you reported earlier?

> Geo3D has a number of distance measurements and a generic way of computing 
> interior distance.  It would be great to take advantage of that for queries 
> that return results ordered by interior distance.
