I think there are many advanced search syntaxes which might be helpful while searching something.
From Who can see other user's Deleted questions and how?, I came to know that one can search own deleted Q's using deleted:1 or deleted:yes
From chatroom, I learnt that user:me search_text can be used to search among own posts and is:q or is:a can be used to specify if we want to search in Questions or Answers.
Are there some other advanced search syntaxes which can be helpful while searching something on Hinduism SE?
