Perhaps you should try some spelling variations:
des besitzes » des ansatzes
yan zwang » yan zhang, yan liang, yuan wang
yan wang » yuan wang, yang yang, qian wang
thing ji » thing _, jing ji, thing 3
ji zhong » 2 zhong, wu zhong, yu zhong
zhong di » zhong tai, zhong zhi, dong di
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 wang)) ((des besitzes) OR (des gesetzes)) thing ji zhong di ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan zwang) OR (yan wang)) ((des besitzes) or (des gesetzes)) thing ji zhong di ;~".
• Adding a wildcard symbol may retrieve word variants: wan ((yan zwang) OR (yan wang)) ((des besitzes) or (des gesetzes)) thing ji zhong di ;*.
