Perhaps you should try some spelling variations:
sin daten » seine daten, von daten, die daten
daten ii » daten iii, daten im, daten vi
ii where » 2 where, 4 where, 1 where
where so » where do, here so, where you
yang jie » yang jin, yang jui, yang yi
yang xi » yang yi, yang jui
so mi » so mai, so i

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 OR long) sin daten ii where so mi ((yang jie) OR (((yang di) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: (dong or long) sin daten ii where so mi ((yang jie) or (((yang di) or (yang xi)))) ;*.
