• If you are trying to use Boolean operators, they must be ALL CAPS: %22agriculture AND state %((25 germany) OR (((((20 germany) OR (5 germany))) OR (7 germany)))) %2f history %((2f 20th) OR (20 20th)) century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %((25 germany) or (((((20 germany) or (5 germany))) or (7 germany)))) %2f history %((2f 20th) OR (20 20th)) century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture and state %((25 germany) or (((((20 germany) or (5 germany))) or (7 germany)))) %2f history %((2f 20th) OR (20 20th)) century%22*.
