I have some notes that contain (for example) only a PDF file. Is there a way to find only these notes and add the tag "PDF" to all of them (using f.e. the desktop version of Evernote on Windows or MacOSX) I would also like to do the same with notes that contain a .jpeg, .png or .gif file.
Besides that I think It'll be great to find all notes that contain a URL in the metadata, this would allow users to add a tag based on the source of a note that was created with the webclipper by clipping a file from a certain domain (f.e. a jpeg file from the facebook CDN "fbcdn" or a file from Twitter's CDN aka "twimg")
