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) OR (2 formulae))%2.2 receipts%((12 prescription) OR (tcm prescriptions)) %2f early works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22medicine %((2f formulae) OR (2 formulae))%2.2 receipts%((12 prescription) or (tcm prescriptions)) %2f early works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22medicine %((2f formulae) OR (2 formulae))%2.2 receipts%((12 prescription) or (tcm prescriptions)) %2f early works to 1800%22*.
