Just commenting here for visibility and support.
My use case is that I have a #scope supertag in my workspace. Every other supertag can have a scope (i.e., "Personal," "Professional," but then also getting specific in those domains like "Coding" or "Music").
However, every scope itself can also have a scope. For instance, I have a scope for my novel, so I can easily query it for all people, places, tasks, etc., related to that novel. That scope in turn has an "Authored" scope.
Sometimes I want to query, for instance, all "Authored" work (as separate from the real world), but to do that, I'd need to query everything with a scope where that scope's scope is "Authored." Sad that there's no way to do that.
Your specific use-case is already covered by Tana. Enable the "part of" semantic function for your
>Scopefield in the advanced setting of the field configuration. You can then use theCOMPONENTS RECsearch operator to perform the queries you want. See the docs:https://tana.inc/docs/semantic-function
