• If you are trying to use Boolean operators, they must be ALL CAPS: %22medicine %2f formulae%((2c receipts) OR (((2.2 receipts) OR (2.2 receptors))))%((2 prescription) OR (tcm prescriptions)) %((2f early) OR (22 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22medicine %2f formulae%((2c receipts) or (((2.2 receipts) OR (2.2 receptors))))%((2 prescription) or (tcm prescriptions)) %((2f early) or (22 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22medicine %2f formulae%((2c receipts) or (((2.2 receipts) OR (2.2 receptors))))%((2 prescription) or (tcm prescriptions)) %((2f early) or (22 early)) works to 1800%22*.
