Perhaps you should try some spelling variations:
zgreat britain » great britain, xgreat britain, great brittain
2f foreign » 2 foreign, 23 foreign, 24 foreign
23 denmark » 2.3 denmark, 3 denmark, 13 denmark
2 denmark » 5 denmark, 4 denmark, 3 denmark
2f early » 24 early, 21 early, 22 early
20 early » 10 early, 1820 early, 1720 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: %zgreat britain %2f foreign relations %((((2 denmark) OR (_ denmark))) OR (23 denmark)) %((2f early) OR (20 early)) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%zgreat britain %2f foreign relations %((((2 denmark) OR (_ denmark))) or (23 denmark)) %((2f early) or (20 early)) works to 1800%22*".
