• If you are trying to use Boolean operators, they must be ALL CAPS: %22christian ((design conversations) OR (design construction)) %2f germany %((((imf history) OR (ref history))) OR (bief history)) %2f 18th century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22christian ((design conversations) OR (design construction)) %2f germany %((((imf history) or (ref history))) or (bief history)) %2f 18th century%22".
• Adding a wildcard symbol may retrieve word variants: %22christian ((design conversations) OR (design construction)) %2f germany %((((imf history) or (ref history))) or (bief history)) %2f 18th century%22*.
