Perhaps you should try some spelling variations:
20th century » 18th century
imf history » brief history
11 germany » 1918 germany, 7 germany, 8 germany
2 germany » 7 germany, 8 germany, 5 germany
11 german » 1 german
2 german » a german, 5 german, 3 german
2f 20th » 20 20th, 2.2 20th

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: %22agriculture AND state %((((2 germany) OR (2 german))) OR (((11 germany) OR (11 german)))) %imf history %2f 20th century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %((((2 germany) or (2 german))) or (((11 germany) OR (11 german)))) %imf history %2f 20th century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture and state %((((2 germany) or (2 german))) or (((11 germany) OR (11 german)))) %imf history %2f 20th century%22*.
