Perhaps you should try some spelling variations:
during crisis » during crises, housing crisis
using risk » during risk, using rs, funding risk
wang yang » wang yan, wang liang, wang yanling
yang ying » yang yang, yang jing, huang ying
how shih » how six
ying eu » ying zhu, using eu, ying hua
eu cost » au costa, der cost, end cost
how she » how some, how safe

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