11 germany » 1918 germany, 8 germany, 5 germany
11 german » 1 german
2 germany » 2 german, 8 germany, 5 germany

• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture AND state %((7 germany) OR (((((11 germany) OR (11 german))) OR (2 germany)))) %imf history %2020 20th century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture AND state %((7 germany) OR (((((11 germany) OR (11 german))) OR (2 germany)))) %imf history %2020 20th century%22*.
