• The words AND, OR and NOT may confuse the search; try adding quotes: "%22medicine %((2 formulas) or (20 formula))%c receipts%((2 prescription) OR (22 prescription)) %((2f early) or (20 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22medicine %((2 formulas) or (20 formula))%c receipts%((2 prescription) OR (22 prescription)) %((2f early) or (20 early)) works to 1800%22*.
