stackoverflow

• user:mine or user:me (or any user id) returns only your posts (or only the posts from whichever user whose id you entered)
• infavorites:mine (or any user id) returns only questions that you (or the user whose id you entered) have favorited.
• intags:mine returns only posts that appear in tags you have marked as favorite. (If you don't have any tags, this operator does nothing. For better results, update your preferences.)
