Perhaps you should try some spelling variations:
zgreat britain » great britain, xgreat britain, great brittain
24 foreign » 4 foreign, 2 foreign, 14 foreign
2f denmark » 2 denmark, 22 denmark, 23 denmark
1720 early » 1727 early, 1820 early, 1770 early
sf early » ef early, f early, self early
20 early » 10 early, 1820 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: %zgreat britain %24 foreign relations %2f denmark %((((sf early) OR (((20 early) OR (1720 early))))) OR (21 early)) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%zgreat britain %24 foreign relations %2f denmark %((((sf early) or (((20 early) OR (1720 early))))) or (21 early)) works to 1800%22*".
