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