Perhaps you should try some spelling variations:
design conversations » design conclusions, design consideration, design competitions
20th century » 18th century
2f germany » 2 germany, 20 germany, 21 germany
2f history » imf history, etf history, ref history
2f 20th » 20 20th, 2.2 20th

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

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