Think this request should return the same number of results like the first one because (0,0,180,90) is total inside, or intersects with (-180,-90,180,90)
Changing to use geo_shape with relation:intersects gives the same result. The current query is intersected. More needs to be done to understand what is going on here.
I make a request with the bbox (whole world) and it works now.

And in your response the geometry information (georss:box) is also the whole world
Then I reduced the bbox to one fouth of the map

With that request I have no thing
