9.13 germany » 9.14 germany, 9.15 germany, 9.16 germany
2.1 germany » 21 germany, 2017 germany, 9.14 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 conversations %((((2.1 germany) OR (9.13 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 conversations %((((2.1 germany) OR (9.13 germany))) or (11 german)) %imf history %2f 18th century%22".
• Adding a wildcard symbol may retrieve word variants: %christians when conversations %((((2.1 germany) OR (9.13 germany))) or (11 german)) %imf history %2f 18th century%22*.
