• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture AND state %2f germany %2f history %((20 20th) OR (((((90 20th) OR (94 20th))) OR (((1994 20th) OR (1995 20th)))))) century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture AND state %2f germany %2f history %((20 20th) OR (((((90 20th) OR (94 20th))) OR (((1994 20th) OR (1995 20th)))))) century%22*.
