The word has only one 'f'.

Well, that's a different word. I would expect "riffling" is the one wanted here. Like thumbing through a book for instance? Rifling, on the other hand, suggests the owner of the things being rifled through probably doesn't (or wouldn't) approve.

P.S. If "riffle" is what is meant, the word "through" should be re-inserted.
