Ignacio Vera commented on LUCENE-7941:
--------------------------------------
[~daddywri], this is exactly the discussion I wanted to rise.
The contract of intersects(GeoShape geoShape) says: "Assess whether a shape
intersects with any of the edges this shape." Therefore the current
implementation is valid as there is no edges in GeoDegeneratedPoint.
Respect the other intersects method, the key lies in the word "shape". We are
trying to make a point behave like a shape. It does not make sense that a point
shape intersects a plane of another shape and the spatial relationship is
WITHIN/CONTAINS. But I see that the getRelationship contract says:
"t is permissible to return OVERLAPS instead of WITHIN if the shape intersects
with the area at even a single point."
I would say that overlaps should be better than within. Therefore point shapes
should return OVERLAPS if they lay in an edge.
Make sense?

> 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.
