23 foreign » 3 foreign, 2 foreign, 13 foreign
2f denmark » 2 denmark, 22 denmark, 23 denmark
self early » relief early
sf early » ef early, imf early, 7 early
21 early » 2.1 early, 1 early, 11 early
f early » ef early, 7 early, 9 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 %2f denmark %((((((f early) OR (((sf early) OR (self early))))) OR (8 early))) OR (21 early)) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%xgreat britain %23 foreign relations %2f denmark %((((((f early) or (((sf early) OR (self early))))) or (8 early))) or (21 early)) works to 1800%22*".
