Ignacio Vera commented on LUCENE-8634:
--------------------------------------
Mostly, the Morton optimisation order the points on the encoding space, but not
sure how relevant it is. Anyway, this should only be relevant if you are
defining your polygons with centimetre accuracy which it is probably not
realistic.
> LatLonShape: Query with the same polygon that is indexed might not match

> If a polygon with a degenerated dimension is indexed and then an intersect
> query is performed with the same polygon, it might result in an empty result.
> For example this polygon with degenerated longitude:
> POLYGON((1.401298464324817E-45 22.0, 1.401298464324817E-45 69.0,
> 4.8202184588118395E-40 69.0, 4.8202184588118395E-40 22.0,
> 1.401298464324817E-45 22.0))
