Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing tan » sharing tags, sharing a, sharing bad
wang liang » wang yang
liang ying » liang liying, huang ying, zhang ying
macd cost » land cost, macd loss
sara » stara, saura
sar » star, saur

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang ying macd cost sharing tan ((hong sara) OR (kong sar)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang ying macd cost sharing tan ((hong sara) OR (kong sar)) ;*.
