Hey all,

I am trying to come up with a search string which would only show me books which have a certain format type. So I am trying to get books which only have a RAR type. But I want to exclude any book with RAR and any other format.

I have been trying to figure out a string which would return these book types, but haven't found a way, and was hoping someone in the community knew how to do this.
