Search within Search/Tags

It would be great to be able to search within the search results. For instance, if I tag several items as #important or #to_review, it would be great to be able to click on those tags and then search within the children of those items for some other keywords, or other tags, etc.

UPDATE: Just learned that if you press F3, it brings up a page search bar in Chrome. So feel free to ignore the request above.

Yeah F3 or Ctrl+G works in Chrome. It’s true that desktop app doesn’t have this capability though.
