Perhaps you should try some spelling variations:
when soft » when so, when some
wang yang » wang yan, wang liang, wang yanling
das weib » das web, das leib, das weite
yang jie » yang jin, yang jui, yang xi
dong di » dong sin
yang yi » yang xi, yang jui
di das » ii das, vi das, xi das

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: dong di das weib when soft ming ((((wang yang) OR (yang jie))) OR (((yang yi) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong di das weib when soft ming ((((wang yang) or (yang jie))) or (((yang yi) or (yang di)))) ;*.
