Perhaps you should try some spelling variations:
22great britain » great britain, zgreat britain, great brittain
xgreat britain » great britain, zgreat britain, great brittain
2f foreign » 2 foreign, 23 foreign, 24 foreign
2f denmark » 23 denmark, 2.3 denmark, 2.4 denmark
22 denmark » 23 denmark, 1.2 denmark, 112 denmark
2f early » 20 early, 22 early, f early
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) OR (xgreat britain)) %2f foreign relations %((2f denmark) OR (((22 denmark) OR (8.2 denmark)))) %((2f early) OR (21 early)) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22great britain) or (xgreat britain)) %2f foreign relations %((2f denmark) or (((22 denmark) OR (8.2 denmark)))) %((2f early) or (21 early)) works to 1800%22*".
