• The words AND, OR and NOT may confuse the search; try adding quotes: "%22christian ((design conversations) or (design conclusions)) %((21 germany) OR (11 germany)) %2f history %((20 20th) or (90 20th)) century%22".
• Adding a wildcard symbol may retrieve word variants: %22christian ((design conversations) or (design conclusions)) %((21 germany) OR (11 germany)) %2f history %((20 20th) or (90 20th)) century%22*.
