Perhaps you should try some spelling variations:
zgreat britain » great britain, xgreat britain, great brittain
23 denmark » 2.3 denmark, 3 denmark, 13 denmark
2 foreign » 3 foreign, 5 foreign, 8 foreign
4 foreign » 3 foreign
2 denmark » _ denmark, 5 denmark, 4 denmark
2.1 early » 1.1 early, 11 early
2f early » 24 early, 20 early, 22 early
21 early » 11 early, 1.1 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 %((2 foreign) OR (4 foreign)) relations %((2 denmark) OR (23 denmark)) %((2f early) OR (((21 early) OR (2.1 early)))) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%zgreat britain %((2 foreign) OR (4 foreign)) relations %((2 denmark) or (23 denmark)) %((2f early) or (((21 early) or (2.1 early)))) works to 1800%22*".
