Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
zhang ming » zhang xin
west how » test how, lost how, cst how
bust how » just how, trust how, out how
ming eu » ming lu, ming yu, making eu
eu cost » au costa, der cost, end cost
bus how » us how, plus how
zhen » zheng, when, chen

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: zhen zhang ming eu cost sharing ((west how) OR (((bust how) OR (bus how)))) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhen zhang ming eu cost sharing ((west how) or (((bust how) OR (bus how)))) shu ;~".
• Adding a wildcard symbol may retrieve word variants: zhen zhang ming eu cost sharing ((west how) or (((bust how) OR (bus how)))) shu ;*.
