In my search results, I want to filter only for notes that I created manually by clicking the New Note button in an Evernote app. I wish to filter out notes which were created by a web clipper or sent to EN by a Share button in some other app. This way, I can readily find my own content. I have started tagging my original content, but I've got many notes that are already created to find.
My first inclination is to find notes with no URL, but I do not find a way to search in URL (am I missing it?)
