Perhaps you should try some spelling variations:
sin dauer » seine dauer, die dauer, i dauer
dauer iv » dauer iii, dauer ist, tauber iv
iv biere » iv bile, iv were, la biere
biere de » pierre de, fievre de, libere de
ying jin » yang jin, jing ji, yang jie
yang xi » yang jui
yang yi » yang jui
dong » doing, long, done

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 sin dauer iv biere de la ((((yang xi) OR (ying jin))) OR (((yang di) OR (yang yi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong sin dauer iv biere de la ((((yang xi) or (ying jin))) or (((yang di) or (yang yi)))) ;*.
