Perhaps you should try some spelling variations:
des ansatzes » des einsatzes, des datensatzes, des gesetzes
yan zhang » yuan chang, bin zhang, han chang
zhang des » zwang des, zugang des, zhang wei
zhong tai » hong hai, zhong zhi
thing ji » thing _, jing ji, thing 3
wang » wing, lang
zhong » zlong
hong » long
tan » than

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: (wang OR wan) yan zhang des ansatzes thing ji ((zhong tai) OR (hong tan)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) yan zhang des ansatzes thing ji ((zhong tai) OR (hong tan)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) yan zhang des ansatzes thing ji ((zhong tai) OR (hong tan)) ;*.
