Perhaps you should try some spelling variations:
your costs » your cost, court costs, your boss
costs data » cost data
taking use » making use, taking up, gating use
yang yang » wang yang, wang yan
dong ping » dong sin, dong bin, dong jung
what your » what you, what's your
qian yan » qian jun, qian yi
use yu » use your

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: ((qian yan) OR (((yang yang) OR (dong ping)))) what your costs data taking use yu ;~.
• Adding a wildcard symbol may retrieve word variants: ((qian yan) or (((yang yang) or (dong ping)))) what your costs data taking use yu ;*.
