• If you are trying to use Boolean operators, they must be ALL CAPS: %22medicine %((2f formulae) OR (20 formulae))%((all receipts) OR (also receipts))%2 prescription %((2f early) OR (20 early)) works to 1800%22.
• Adding a wildcard symbol may retrieve word variants: %22medicine %((2f formulae) or (20 formulae))%((all receipts) or (also receipts))%2 prescription %((2f early) or (20 early)) works to 1800%22*.
