• The words AND, OR and NOT may confuse the search; try adding quotes: "%22christian ((union conversations) OR (win conversations)) %((7 germany) OR (2.1 germany)) %2f history %20 20th century%22".
• Adding a wildcard symbol may retrieve word variants: %22christian ((union conversations) OR (win conversations)) %((7 germany) OR (2.1 germany)) %2f history %20 20th century%22*.
