Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
wang yang » wang yan, wang liang, wang yanling
yang yang » wang yan
yang jin » yang jie, yang jun, ying jin
jin cost » can cost, die cost, run cost
among eu » among men, among _
among 15 » among _

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yang jin cost sharing risk ((among eu) OR (among 15)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yang jin cost sharing risk ((among eu) OR (among 15)) ;*.
