Perhaps you should try some spelling variations:
cases when » cases where, cases what, games when
war cases » war causes, war crises, dar case
when song » when songs, when so, when soft
song min » song ming, gong min, jong min
yang jie » yang jin, yang jui, yang yi
und war » und warum, und waren, und warte
yang xi » yang yi, yang jui
ding » dinge, wing, ping

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: ding und war cases when song min ((((shang jin) OR (yang jie))) OR (((yang di) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: ding und war cases when song min ((((shang jin) or (yang jie))) or (((yang di) or (yang xi)))) ;*.
