Perhaps you should try some spelling variations:
imf history » brief history
2 germany » 12 germany, 7 germany, 2 german
1 german » a german, 3 german, 5 german
2f 20th » 2.2 20th
20 20th » 90 20th, 2019 20th, 2020 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 (((((11 german) OR (1 german))y) OR (((11 german) OR (1 german)))))) %imf history %((2f 20th) OR (20 20th)) century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %((2 germany) or (((((11 german) OR (1 german))y) or (((11 german) OR (1 german)))))) %imf history %((2f 20th) or (20 20th)) century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture and state %((2 germany) or (((((11 german) OR (1 german))y) or (((11 german) OR (1 german)))))) %imf history %((2f 20th) or (20 20th)) century%22*.
