Try looking in the Fixnum class for methods like &, |, ~, <<, and >>.

$ ri '<<'

It gives you all classes containing method '<<', witch for Fixnum
means left bit shift.

Not through ri itself, but ri gets its data from a set of yaml files, so
you could grep those.

Or, rub-a-dub-dub, use yubnub:

and the grd (Google ruby-doc) command

Google accepts assorted quasi regexen stuff, too.

"Fuzzy" is commonly used to refer to a non-exact search
