• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %((2f germany) or (((2 germany) or (7 germany)))) %((2f history) or (imf history)) %((((2020 2021) or (2019 20th))) or (((94 20th) OR (90 20th)))) century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture and state %((2f germany) or (((2 germany) or (7 germany)))) %((2f history) or (imf history)) %((((2020 2021) or (2019 20th))) or (((94 20th) OR (90 20th)))) century%22*.
