I would reiterate this request and I think the author was misunderstood. Tabbles will search through the whole database, but what it wont do is if I go to a particular directory and then try and locate any tagged files within subdirectories either by doing a search or combining with a tabble, then it will not search within the sub folders.
This is particularly useful to have when you are trying to consolidate disparate tagged files around your computer into a single folder.

In the attached picture there are 3000 tagged files under the folder “work” but search or combine with tag “tagged” will not find them
