Perhaps you should try some spelling variations:
christians when » christians who, christians men, christians whom
christians he » christians have, christians held, christians home
2017 germany » 20 germany, 17 germany, 2006 germany
imf history » brief history
11 german » 1 german

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: %((christians when) OR (christians he)) conversations %((2017 germany) OR (11 german)) %imf history %2f 18th century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((christians when) OR (christians he)) conversations %((2017 germany) or (11 german)) %imf history %2f 18th century%22".
• Adding a wildcard symbol may retrieve word variants: %((christians when) OR (christians he)) conversations %((2017 germany) or (11 german)) %imf history %2f 18th century%22*.
