Perhaps you should try some spelling variations:
22great britain » great britain, xgreat britain, zgreat britain
2f foreign » 23 foreign, 24 foreign, 22 foreign
2f denmark » 2 denmark, 22 denmark, 23 denmark
2 foreign » 4 foreign, 5 foreign, 8 foreign
2f early » 24 early, 20 early, 23 early
22 early » 2 early, 12 early, 1722 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 %((2f foreign) OR (((2 foreign) OR (3 foreign)))) relations %2f denmark %((((2f early) OR (22 early))) OR (21 early)) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22great britain %((2f foreign) or (((2 foreign) OR (3 foreign)))) relations %2f denmark %((((2f early) or (22 early))) or (21 early)) works to 1800%22*".
