Perhaps you should try some spelling variations:
when soft » when so, when some
doing un » doing und, doing our, doing von
dann bin » dong bin
bin when » win when, can when, bin we
yang yun » yang jun, tang yun, yang yue
wong yue » wang yue, hong yu
un dann » und dann, um dann, bin dann
yang yi » yang xi, yang jui

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: doing un dann bin when soft min ((((yang yun) OR (wong yue))) OR (((yang di) OR (yang yi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: doing un dann bin when soft min ((((yang yun) or (wong yue))) or (((yang di) or (yang yi)))) ;*.
