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