2f foreign » 2 foreign, 23 foreign, 22 foreign
24 foreign » 4 foreign, 2 foreign, 14 foreign
2f denmark » 2 denmark, 22 denmark, 2.3 denmark

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: %great britain %((2f foreign) OR (24 foreign)) relations %((2f denmark) OR (23 denmark)) %1722 early works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%great britain %((2f foreign) OR (24 foreign)) relations %((2f denmark) or (23 denmark)) %1722 early works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %great britain %((2f foreign) OR (24 foreign)) relations %((2f denmark) or (23 denmark)) %1722 early works to 1800%22*.
