Perhaps you should try some spelling variations:
den songs » when songs
doing von » doing un, ing von
von dann » von dan, von dana, von daten
den jong » de jong, den jena, den job
yang jin » yang jie, yang jun, ying jin
yang jui » yang judy, yang di, yang yi
yang xi » yang di, yang yi

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 von dann xxii ((den jong) OR (den songs)) min ((yang jin) OR (((yang jui) OR (yang xi)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doing von dann xxii ((den jong) OR (den songs)) min ((yang jin) or (((yang jui) or (yang xi)))) ;~".
• Adding a wildcard symbol may retrieve word variants: doing von dann xxii ((den jong) OR (den songs)) min ((yang jin) or (((yang jui) or (yang xi)))) ;*.
