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