2.3 denmark » 2.4 denmark, 13 denmark, 2 denmark
23 foreign » 3 foreign, 2 foreign, 13 foreign
23 denmark » 13 denmark, 2 denmark, 22 denmark
2f early » 20 early, 21 early, 22 early
24 early » 4 early, 14 early, 1724 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 %23 foreign relations %((2.3 denmark) OR (23 denmark)) %((2f early) OR (24 early)) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%xgreat britain %23 foreign relations %((2.3 denmark) or (23 denmark)) %((2f early) OR (24 early)) works to 1800%22*".
