Perhaps you should try some spelling variations:
22christian design » unchristian design, christian designed
design conclusions » design conclusion
1918 germany » 8 germany
2.1 germany » 21 germany, 2017 germany, 9.13 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 design conclusions %((2.1 germany) OR (1918 germany)) %2f history %2.2 ((20th century) OR (18th century))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22christian design conclusions %((2.1 germany) or (1918 germany)) %2f history %2.2 ((20th century) OR (18th century))%22".
• Adding a wildcard symbol may retrieve word variants: %22christian design conclusions %((2.1 germany) or (1918 germany)) %2f history %2.2 ((20th century) OR (18th century))%22*.
