• If you are trying to use Boolean operators, they must be ALL CAPS: %22agriculture AND state %((2f germany) OR (((12 germany) OR (7 germany)))) %((2f history) OR (imf history)) %((((2020 2021) OR (((2019 20th) OR (2019 5th))))) OR (94 20th)) century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %((2f germany) or (((12 germany) or (7 germany)))) %((2f history) or (imf history)) %((((2020 2021) or (((2019 20th) OR (2019 5th))))) or (94 20th)) century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture and state %((2f germany) or (((12 germany) or (7 germany)))) %((2f history) or (imf history)) %((((2020 2021) or (((2019 20th) OR (2019 5th))))) or (94 20th)) century%22*.
