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