• If you are trying to use Boolean operators, they must be ALL CAPS: %22agriculture AND state %((((((25 germany) OR (5 germany))) OR (21 germany))) OR (11 german)) %etf history %2f 18th century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %((((((25 germany) OR (5 germany))) or (21 germany))) or (11 german)) %etf history %2f 18th century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture and state %((((((25 germany) OR (5 germany))) or (21 germany))) or (11 german)) %etf history %2f 18th century%22*.
