I've got a 1500+ page document and I need to know if there are any pages that begin or end with a double paragraph mark (^p^p). I want to insert a separator line to avoid any confusion when reading.

Is there a way to search a specific line number, on every page, for a specific character or word?

Also, when the document converted into Word, it removed the space after all italic words. For example: "I had a reallyhard time." Is there a way to search for italic characters NOT followed by a space? I've been using spell check to find these, but I'd like to focus on this issue instead of spell-checking the whole 1500 page document.
