Perhaps you should try some spelling variations:
22great britain » xgreat britain, zgreat britain, great brittain
2f foreign » 2 foreign, 23 foreign, 24 foreign
22 denmark » 1.2 denmark, 112 denmark, 2.3 denmark
23 denmark » 2.3 denmark, 3 denmark, 83 denmark
13 denmark » 3 denmark, 1 denmark, _ denmark
2f early » 24 early, 20 early, 21 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) OR (great britain)) %2f foreign relations %((((22 denmark) OR (8.2 denmark))) OR (((23 denmark) OR (13 denmark)))) %2f early works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22great britain) or (great britain)) %2f foreign relations %((((22 denmark) OR (8.2 denmark))) or (((23 denmark) or (13 denmark)))) %2f early works to 1800%22*".
