2c prescriptions » _ prescriptions, 2 prescription, 21 prescription
2.2 receipts » 2.3 receipts, 25 receipts, 6.2 receipt
20 formulae » 10 formulae, 2 formulae, 20 formule
20 formula » 2 formula, 25 formula, 20 formule

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 %((20 formulae) OR (20 formula))%2.2 receipts%((2c prescriptions) OR (tcm prescriptions)) %2f early works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22medicine %((20 formulae) OR (20 formula))%2.2 receipts%((2c prescriptions) or (tcm prescriptions)) %2f early works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22medicine %((20 formulae) OR (20 formula))%2.2 receipts%((2c prescriptions) or (tcm prescriptions)) %2f early works to 1800%22*.
