23 foreign » 3 foreign, 2 foreign, 13 foreign
2f denmark » 2 denmark, 22 denmark, 2.3 denmark
23 denmark » 2.3 denmark, 3 denmark, 13 denmark
22 early » 2 early, 1722 early, 1.2 early

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 (23 foreign)) relations %((2f denmark) OR (23 denmark)) %((22 early) OR (12 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%great britain %((2f foreign) OR (23 foreign)) relations %((2f denmark) or (23 denmark)) %((22 early) or (12 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %great britain %((2f foreign) OR (23 foreign)) relations %((2f denmark) or (23 denmark)) %((22 early) or (12 early)) works to 1800%22*.
