Perhaps you should try some spelling variations:
cases while » cases where, tasks while, careers while
while song » whale song, while doing, while using
und dann » und dank, und daten, und denen
song min » song ming, gong min, jong min
ying jin » yang jin, jing ji
yang jie » yang jin, yang jui, yang xi
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 dann cases while song min ((((ying jin) OR (yang jie))) OR (((yang di) OR (yang yi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: ding und dann cases while song min ((((ying jin) or (yang jie))) or (((yang di) or (yang yi)))) ;*.
