Perhaps you should try some spelling variations:
design conversations » design considerations, design construction, design conclusions
union conversations » win conversations, driven conversations, invent conversations
2.1 germany » 2017 germany, 9.13 germany, 9.14 germany
21 germany » 11 germany, 2 germany, 20 germany
2f history » imf history, etf history, ref history

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 ((union conversations) OR (design conversations)) %((7 germany) OR (((2.1 germany) OR (21 germany)))) %2f history %2f 18th century%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22christian ((union conversations) or (design conversations)) %((7 germany) or (((2.1 germany) OR (21 germany)))) %2f history %2f 18th century%22*".
