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