Karl Wright commented on LUCENE-7941:
-------------------------------------

Nope, that will break getRelationship() as all WITHIN shapes will return
OVERLAPS. The method checks if a shape goes in and out (cross and edge) of a
shape, therefore OVERLAPS.
{quote}
But that is legal, although not ideal:
{code}
* It is permissible to return OVERLAPS instead of WITHIN if the shape
* intersects with the area at even a single point.
{code}
I would opt for this in the case of GeoDegeneratePoint.
> GeoDegeneratePoints return intersects when located in edge shape

> If the degenerate Geopoint lays on the boundary of a shape, the
> relationships between the objects are not symetrical:
> The bounding box "thinks" it contains the degenerated point.
> The degenerated point "thinks" it intersects the shape.
