[OWSLib-users] CSW query for datasets intersecting bounding box

[Signell, Richard]

On closer inspection, it appears that fes.BBox(bbox) is returning
datasets that are (1) completely within or (2) overlapping, but not
datasets where the bbox of interest is itself completely contained
within the dataset bounding box.

So it's not finding my dataset that is the whole US East Coast when I
specify New York Harbor because the the bounding box for New York
Harbor is completely within the bounding box for the US East Coast.

So I'm will wondering how to find my US East Coast model result with
my New York Harbor bbox, and more generally, how to specify these
different behaviors with OWSLib fes.
