Perhaps you should try some spelling variations:
tcm prescriptions » tcm prescription, some prescriptions, test prescriptions
2 prescription » 12 prescription, 21 prescription, 22 prescription
2f formulae » 2 formulae, 20 formulae, dnf formulae
25 receipts » 5 receipts, _ receipts, c receipts
2f early » 20 early, ef early, f early
21 early » 2.1 early, 1 early, 11 early

Try widening your search to All Fields.

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%25 receipts%((2 prescription) OR (tcm prescriptions)) %((2f early) OR (21 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22medicine %2f formulae%25 receipts%((2 prescription) or (tcm prescriptions)) %((2f early) OR (21 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22medicine %2f formulae%25 receipts%((2 prescription) or (tcm prescriptions)) %((2f early) OR (21 early)) works to 1800%22*.
