• If you are trying to use Boolean operators, they must be ALL CAPS: %22christian ((design conversations) OR (design conclusions)) %((((21 germany) OR (2 germany))) OR (2.1 germany)) %2f history %((2f 20th) OR (((2019 20th) OR (2019 6th)))) century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22christian ((design conversations) or (design conclusions)) %((((21 germany) OR (2 germany))) or (2.1 germany)) %2f history %((2f 20th) or (((2019 20th) or (2019 6th)))) century%22".
• Adding a wildcard symbol may retrieve word variants: %22christian ((design conversations) or (design conclusions)) %((((21 germany) OR (2 germany))) or (2.1 germany)) %2f history %((2f 20th) or (((2019 20th) or (2019 6th)))) century%22*.
