some descriptions » some prescriptions, site descriptions, game descriptions
tcm prescriptions » tcm prescription, some prescriptions, test prescriptions
2 prescription » 12 prescription, 21 prescription, 22 prescription
2f formulae » 20 formulae, dnf formulae, 2.8 formulae
2c receipts » c receipts, 25 receipts, 2.2 receipts
2 formulae » 20 formulae, _ formulae, 2 formulas
2f early » 24 early, 20 early, 21 early

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

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