i think this functionality should be implemented with search operators so advanced users can type their search query rather than trying to use the ui. and more than just location operators should be made available. initial release should include operators for every option currently available in advanced search with the ability to invert or negate an operator. later releases should add searching by attachment type, attachment size, starred, and others that have been suggested throughout topics on uservoice.
