• If you are trying to use Boolean operators, they must be ALL CAPS: %22agriculture AND state %((2f germany) OR (21 germany)) %imf history %((((2021 20th) OR (((2021 10th) OR (2021 16th))))) OR (2020 5th)) century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %((2f germany) or (21 germany)) %imf history %((((2021 20th) or (((2021 10th) OR (2021 16th))))) or (2020 5th)) century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture and state %((2f germany) or (21 germany)) %imf history %((((2021 20th) or (((2021 10th) OR (2021 16th))))) or (2020 5th)) century%22*.
