Perhaps you should try some spelling variations:
old raincoat » _ raincoat
won't ever » don't ever, won't even, don't every
ever let » never let, ever lost, meyer let
you down » you own, you doing, you done

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "an old raincoat won't ever let ((you down) OR (you do))".
• Adding a wildcard symbol may retrieve word variants: an old raincoat won't ever let ((you down) OR (you do))*.
