Perhaps you should try some spelling variations:
des besitzes » des ansatzes
yan zwang » yan wang, yan liang, yuan wang
yan zhang » yuan chang, bin zhang, han chang
zhong tai » hong tan, hong hai, zhong zhi
thing ji » thing _, jing ji, thing 3
ji zhong » 2 zhong, wu zhong, yu zhong
gesetzes » gesetze, gesetz

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