Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
sharing a » sharing _
yue cost » true cost, type cost, use cost
wang yue » wong yue, wang hua, wang yan
hong yu » wong yue

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