Achim Let's work it through.
Let's say we have a large publishing project with lots of tags. Some (not all) of the tags are in tag groups. #+TAGGROUP: :characteristic: :colour:mass:material: #+TAGGROUP: :colo(u)r: :red:green:blue: #+TAGGROUP: :red: :crimson:scarlet:brick: Our ungrouped tags are unrelated things like :name: and :event:. Exporting tag :colour: would export :red: :crimson: :scarlet: :brick: :green: and :blue:. Would it be useful to include :characteristic:? I'd say yes, as an option.

If I've read the OP correctly, this should be (optionally?) transitive, i.e. searches for :red: should also return entries with just :color:. Regards, Achim.
