Perhaps you should try some spelling variations:
sin dauer » seine dauer, die dauer, i dauer
where do » where _
yang jie » yang jin, yang jui, yang yi
dauer 1 » dauer 2, dauer _, dauer 1.4
1 where » 2 where, 4 where
yang xi » yang yi, yang jui
do fi » do fdi
dong » doing, long, done

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: dong sin dauer 1 where do fi ((yang jie) or (((yang di) or (yang xi)))) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: dong sin dauer 1 where do fi ((yang jie) OR (((yang di) OR (yang xi)))) ;*.
