Perhaps you should try some spelling variations:
cost sharing » cost savings
yang kang » yang yang, yang guang, yang liang
min hong » amin hong, tin hong, min hyoung
yang ka » yang fan, yang yao
yang xi » yang di, yang yi, yang jui
hong a » hong ma, hong w, kong a
ya a » a a, y a, ye a

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang ka) or (yang kang))) or (yang xi))ng ya a ((cost sharing) OR (risk sharing)) min hong a ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang ka) OR (yang kang))) OR (yang xi))ng ya a ((cost sharing) OR (risk sharing)) min hong a ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang ka) or (yang kang))) or (yang xi))ng ya a ((cost sharing) OR (risk sharing)) min hong a ;".
• Adding a wildcard symbol may retrieve word variants: ((((yang ka) or (yang kang))) or (yang xi))ng ya a ((cost sharing) OR (risk sharing)) min hong a ;*.
