• If you are trying to use Boolean operators, they must be ALL CAPS: %22agriculture AND state %((((2f germany) OR (25 germany))) OR (20 germany)) %etf history %((((((20 20th) OR (2023 20th))) OR (20((20 20th) OR (2023 20th))))) OR (90 20th)) century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %((((2f germany) or (25 germany))) or (20 germany)) %etf history %((((((20 20th) OR (2023 20th))) or (20((20 20th) OR (2023 20th))))) or (90 20th)) century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture and state %((((2f germany) or (25 germany))) or (20 germany)) %etf history %((((((20 20th) OR (2023 20th))) or (20((20 20th) OR (2023 20th))))) or (90 20th)) century%22*.
