Perhaps you should try some spelling variations:
sales when » cases when, rules when
war sales » car sales, water sales, farm sales
when song » when songs, when so, when soft
song ming » song bing, song min, gong min
yang jie » yang jin, yang jui, yang xi
und war » und warum, und waren, und warte
yang yi » yang xi, 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 sales when song ming ((((shang jin) OR (yang jie))) OR (((yang di) OR (yang yi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: ding und war sales when song ming ((((shang jin) or (yang jie))) or (((yang di) or (yang yi)))) ;*.
