Perhaps you should try some spelling variations:
doing sin » dong sin, doing un, doing von
where so » where do, here so, where you
yang jie » yang jin, yang jui, yang yi
daten 2 » daten 5, daten b, daten 3
daten 1 » daten 5, daten b, daten 3
yang xi » yang yi, yang jui
so i » so im, so mi, son 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: doing sin ((daten 2) OR (daten 1)) where so i ((yang jie) OR (((yang di) OR (yang xi)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doing sin ((daten 2) OR (daten 1)) where so i ((yang jie) or (((yang di) or (yang xi)))) ;~".
• Adding a wildcard symbol may retrieve word variants: doing sin ((daten 2) OR (daten 1)) where so i ((yang jie) or (((yang di) or (yang xi)))) ;*.
