Perhaps you should try some spelling variations:
25 germany » 5 germany, 20 germany, 21 germany
2f history » 2.1 history, imf history, etf history
2 germany » 12 germany, 2 german, 8 germany
2019 5th » 2019 4th, 2019 6th
94 24th » 94 4th, 94 14th, 24 24th

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: %22agriculture AND state %((((25 germany) OR (2 germany))) OR (7 germany)) %2f history %((2019 5th) OR (94 24th)) century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %((((25 germany) OR (2 germany))) or (7 germany)) %2f history %((2019 5th) or (94 24th)) century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture and state %((((25 germany) OR (2 germany))) or (7 germany)) %2f history %((2019 5th) or (94 24th)) century%22*.
