• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %((7 germany) or (21 germany)) %imf history %((((90 20th) OR (1990 20th))) or (2020 20th)) century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture and state %((7 germany) or (21 germany)) %imf history %((((90 20th) OR (1990 20th))) or (2020 20th)) century%22*.
