Perhaps you should try some spelling variations:
design conversations » design considerations, design construction, design consideration
union conversations » win conversations, driven conversations, invent conversations
21 germany » 2.1 germany, 11 germany, 2 germany
2f history » 2.1 history, imf history, etf history

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 ((((union conversations) OR (design conversations))) OR (((design conclusions) OR (design conclusion)))) %21 germany %2f history %20 ((20th century) OR (18th century))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22christian ((((union conversations) OR (design conversations))) or (((design conclusions) or (design conclusion)))) %21 germany %2f history %20 ((20th century) or (18th century))%22".
• Adding a wildcard symbol may retrieve word variants: %22christian ((((union conversations) OR (design conversations))) or (((design conclusions) or (design conclusion)))) %21 germany %2f history %20 ((20th century) or (18th century))%22*.
