Perhaps you should try some spelling variations:
xgreat britain » great britain, zgreat britain, great brittain
2f foreign » 23 foreign, 24 foreign, 22 foreign
22 denmark » 2 denmark, 23 denmark, 8.2 denmark
2 foreign » 3 foreign, 4 foreign, 5 foreign
2f early » 24 early, 20 early, 21 early
11 early » 1 early, 1791 early, 7 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: %xgreat britain %((2f foreign) OR (2 foreign)) relations %22 denmark %((2f early) OR (11 early)) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%xgreat britain %((2f foreign) OR (2 foreign)) relations %22 denmark %((2f early) or (11 early)) works to 1800%22*".
