ftags (folder tags) are tags with a hierarchical structure. For example, a search for "bar" will return all posts ftagged "bar" or any of "bar"s descendents (e.g., "bar/baz"), while a search for "foo/bar" will return posts ftagged "bar" or a descendent of "bar," where "bar" is a child of the ftag "foo" (so: "foo/bar" and "foo/bar/baz" are grabbed, but "bar" and "bar/baz" are not).
