Perhaps you should try some spelling variations:
des ansatzes » des einsatzes, des datensatzes, des gesetzes
dong bin » dong sin, dong di, dann bin
yang jin » yang jun, ying jin, shang jin
yang jie » yang di, yang jui, yang xi
ya des » ca des
hong 7 » hong w, hong g
hong a » hong ma, hong w, kong a
wang » wing, wan, lang

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 yan) OR (dong bin)) ya des ansatzes ((yang jin) OR (yang jie)) ((hong 7) OR (hong a)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (dong bin)) ya des ansatzes ((yang jin) or (yang jie)) ((hong 7) OR (hong a)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (dong bin)) ya des ansatzes ((yang jin) or (yang jie)) ((hong 7) OR (hong a)) ;*.
