Perhaps you should try some spelling variations:
costs using » tests using, costs arising, costs missing
using risk » during risk, using rs, funding risk
risk along » risk among, ask along
yang mind » yang cindy, yang jin, sang minh
along shu » along nhue, cong shu, along who
wang dan » wang yan, wang ban, wang yidan
yang end » yang anda, yang d

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: wang dan ((yang end) OR (yang mind)) costs using risk along shu ;~.
• Adding a wildcard symbol may retrieve word variants: wang dan ((yang end) or (yang mind)) costs using risk along shu ;*.
