Perhaps you should try some spelling variations:
time last » time list, time past, time lost
thin zeng » thin end, thin lens
dong sind » dong bin, dong ping
yan yang » yang yang, dan yang, tan yang
yao yang » yang yang
time pad » time part, time pcr
sind » signd, skind, seind
sin » sign, skin, sein

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: wai ((yan yang) OR (yao yang)) ((time last) OR (time pad)) thin zeng ((dong sind) OR (dong sin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai ((yan yang) OR (yao yang)) ((time last) or (time pad)) thin zeng ((dong sind) or (dong sin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wai ((yan yang) OR (yao yang)) ((time last) or (time pad)) thin zeng ((dong sind) or (dong sin)) ;*.
