Perhaps you should try some spelling variations:
22christian design » unchristian design, christian designed
design conclusions » design conclusion
20th century » 18th century
21 germany » 2.1 germany, 11 germany, 2 germany
2f history » 2.1 history, imf history, etf history
8 germany » 7 germany
2.2 20th » 2020 20th, 2023 20th, 2021 20th

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 %((21 germany) OR (((1918 germany) OR (8 germany)))) %2f history %2.2 20th century%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22christian design conclusions %((21 germany) or (((1918 germany) OR (8 germany)))) %2f history %2.2 20th century%22*".
