Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
yang yang » wang yang, wang yan
sharing a » sharing _
yan yang » yao yang, tan yang, yan wang
dan yang » daun yang, tan yang, wang yang
run cost » iran cost, can cost, run cash
wong yue » wang yue, hong yu
a wong » y wong

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: zhang ((((yan yang) OR (yang yang))) OR (dan yang)) run cost sharing a wong yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang ((((yan yang) OR (yang yang))) or (dan yang)) run cost sharing a wong yue ;~".
• Adding a wildcard symbol may retrieve word variants: zhang ((((yan yang) OR (yang yang))) or (dan yang)) run cost sharing a wong yue ;*.
