Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
tan ying » ran ying, tan yang, tan yong
fan ying » fan xing, ran ying, jin ying
zhu cost » eu cost
how shih » how six, how she
how shu » how she, how slum

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: cheng ((tan ying) OR (fan ying)) zhu cost sharing risk ((how shu) OR (how shih)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cheng ((tan ying) OR (fan ying)) zhu cost sharing risk ((how shu) or (how shih)) ;~".
• Adding a wildcard symbol may retrieve word variants: cheng ((tan ying) OR (fan ying)) zhu cost sharing risk ((how shu) or (how shih)) ;*.
