• If you are trying to use Boolean operators, they must be ALL CAPS: %22agriculture AND state %((2f germany) OR (1 german)) %etf history %((2.2 20th) OR (2021 20th)) century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %((2f germany) or (1 german)) %etf history %((2.2 20th) OR (2021 20th)) century%22".
