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