Perhaps you should try some spelling variations:
sin dauer » seine dauer, die dauer, i dauer
dauer iii » paper iii, baker iii, dauer ist
iii usage » api usage, ids usage, iii use
long sin » dong sin, long span, long run
usage de » usage des, usages de, l'usage de
yang jin » yang jie, yang jun, ying jin
yang yi » yang jui
yang xi » yang jui
de mi » de ma, de mr, de ti

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: long sin dauer iii usage de mi ((((yang jin) OR (yang yi))) OR (((yang di) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: long sin dauer iii usage de mi ((((yang jin) or (yang yi))) or (((yang di) or (yang xi)))) ;*.
