Perhaps you should try some spelling variations:
22great britain » great britain, xgreat britain, zgreat britain
2f foreign » 2 foreign, 23 foreign, 24 foreign
23 denmark » 2.3 denmark, 3 denmark, 13 denmark
2 denmark » _ denmark, 4 denmark, 3 denmark
5 denmark » _ denmark
21 early » 2.1 early, 1 early, 11 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: %22great britain %2f foreign relations %((((2((2 denmark) OR (5 denmark))) OR (((2 denmark) OR (5 denmark))))) OR (23 denmark)) %21 early works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22great britain %2f foreign relations %((((2((2 denmark) OR (5 denmark))) or (((2 denmark) OR (5 denmark))))) or (23 denmark)) %21 early works to 1800%22*".
