Perhaps you should try some spelling variations:
tcm prescriptions » tcm prescription, some prescriptions, test prescriptions
12 prescription » 10 prescription, 11 prescription, 16 prescription
2f formulae » 2 formulae, 20 formulae, dnf formulae
2c receipts » c receipts, 2.2 receipts, 2.3 receipts
25 receipts » 5 receipts, _ receipts, c receipts
2f early » 24 early, 20 early, 21 early

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: "%22medicine %2f formulae%((2c receipts) OR (25 receipts))%((12 prescription) OR (tcm prescriptions)) %2f early works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22medicine %2f formulae%((2c receipts) OR (25 receipts))%((12 prescription) OR (tcm prescriptions)) %2f early works to 1800%22*.
