Perhaps you should try some spelling variations:
funding risk » funding list, building risk, fund risk
huang ying » huang jing, huang ting, huang yang
using risk » during risk, using rs, rising risks
yang ying » yang yang, yang jing, liang ying
au costa » can costa, _ costa, da costa
how shih » how six, how she

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 ((yang ying) OR (huang ying)) au costa ((using risk) OR (funding risk)) how shih ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang ying) OR (huang ying)) au costa ((using risk) or (funding risk)) how shih ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang ying) OR (huang ying)) au costa ((using risk) or (funding risk)) how shih ;*.
