Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing a » sharing _
wang dan » wang ban, wang yang, liang dan
yang can » yang fan, yang dean, yang yang
can cost » can costa, can lost, can post
wong sam » wong sau, wong lai, kong sar
hong ng » hong kong, hong jong, hong hong

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