Perhaps you should try some spelling variations:
2c prescriptions » tcm prescriptions, _ prescriptions, 2 prescription
iii receipts » quit receipts, iii recent, new receipts
2f formulae » 2 formulae, dnf formulae, 2.8 formulae
20 formulae » 10 formulae, 2 formulae, 20 formula
c receipts » cash receipts, new receipts, all receipts
22 early » 2 early, 12 early, 1722 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) OR (20 formulae))%((((c receipts) OR (iii receipts))) OR (_ receipts))%2c prescriptions %22 early works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22medicine %((2f formulae) OR (20 formulae))%((((c receipts) OR (iii receipts))) OR (_ receipts))%2c prescriptions %22 early works to 1800%22*.
