Perhaps you should try some spelling variations:
21 germany » 11 germany, 2 germany, 20 germany
2f history » imf history, etf history, ref history
2020 20th » 2020 16th, 2020 2021, 2020 5th
2.2 20th » 2023 20th, 2021 20th, 2022 20th
20 20th » 90 20th, 2019 20th, 2023 20th

• If you are trying to use Boolean operators, they must be ALL CAPS: %22agriculture AND state %21 germany %2f history %((((2f 20th) OR (2.2 20th))) OR (((20 20th) OR (2020 20th)))) century%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22agriculture and state %21 germany %2f history %((((2f 20th) or (2.2 20th))) or (((20 20th) OR (2020 20th)))) century%22".
• Adding a wildcard symbol may retrieve word variants: %22agriculture and state %21 germany %2f history %((((2f 20th) or (2.2 20th))) or (((20 20th) OR (2020 20th)))) century%22*.
