Perhaps you should try some spelling variations:
design conversations » design considerations, design construction, design conclusions
union conversations » win conversations, driven conversations, invent conversations
12 germany » 11 germany, 2 germany, 14 germany
12 german » 2 german, 2012 german
20 18th » 2017 18th, 2021 18th, 2018 18th

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)) %((12 germany) OR (12 german)) %brief history %20 18th century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22christian ((union conversations) or (design conversations)) %((12 germany) OR (12 german)) %brief history %20 18th century%22".
• Adding a wildcard symbol may retrieve word variants: %22christian ((union conversations) or (design conversations)) %((12 germany) OR (12 german)) %brief history %20 18th century%22*.
