Question about spatialRelator
I would like to use the spatialRelator to test if a requestor intersects a candidate but excluding those where it is only the boundaries that touch the candidate.

Hi,
You can control kinds of spatial relationships that should be detected with the "Tests to Perform" parameter. Try this setting to exclude the TOUCHES relation.

In addition to testing for relations_pass-criteria = Touches, as Takashi suggests, you also need to check its cardinality:
_relationships{0}.card_line > 0
Set "calculate cardinality" = Yes.
Expose the attribute(s).
That is, if u wish to exclude objects that only touch by a point ( _relationships{0}.card_point > 0)
