Perhaps you should try some spelling variations:
tcm prescriptions » tcm prescription, some prescriptions, test prescriptions
2c prescriptions » _ prescriptions, 2 prescription, 21 prescription
dnf formulae » dnf formulas, cdnf formulas, cnf formulas
2.2 receipts » 2.3 receipts, 25 receipts, 6.2 receipt
1722 early » 1727 early
22 early » 2 early, 12 early, 1.2 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 %dnf formulae%2.2 receipts%((2c prescriptions) OR (tcm prescriptions)) %((22 early) OR (1722 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22medicine %dnf formulae%2.2 receipts%((2c prescriptions) or (tcm prescriptions)) %((22 early) OR (1722 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22medicine %dnf formulae%2.2 receipts%((2c prescriptions) or (tcm prescriptions)) %((22 early) OR (1722 early)) works to 1800%22*.
