• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %((((2 germany) OR (12 germany))) or (2.1 germany)) %imf history %2f 18th century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture and state %((((2 germany) OR (12 germany))) or (2.1 germany)) %imf history %2f 18th century%22*.
