• If you are trying to use Boolean operators, they must be ALL CAPS: %22agriculture AND state %((2 germany) OR (2 german)) %((2f history) OR (imf history)) %((2.2 20th) OR (2020 20th)) century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %((2 germany) or (2 german)) %((2f history) or (imf history)) %((2.2 20th) OR (2020 20th)) century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture and state %((2 germany) or (2 german)) %((2f history) or (imf history)) %((2.2 20th) OR (2020 20th)) century%22*.
