Firefox needs the ability to search ONLY by tag, without matching content/titles. As a web developer, I have started tagging user experience site bookmarks with the tag "UX". However, I am also a Linux user with appropriate bookmarks. So, when I try searching either bookmarks or via awesomebar, "UX" brings up BOTH items tagged "UX" and anything with "Linux" in it. It would be good to have a symbol/prefix that constrains the search to STRICTLY tags, which might allow me to only have the UX items up.
