Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing bad » sharing a, sharing 3d, sharing big
yang run » yang jun, long run, bank run
yang yun » yang jun, tang yun, yang yue
hand auf » handel auf, und auf, hand dug
hand yu » hand zu, hand dug, hand eye
wang » wing, lang

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 OR wan) dan ((yang run) OR (yang yun)) cost sharing bad ((hand yu) OR (hand auf)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) dan ((yang run) or (yang yun)) cost sharing bad ((hand yu) OR (hand auf)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) dan ((yang run) or (yang yun)) cost sharing bad ((hand yu) OR (hand auf)) ;*.
