Perhaps you should try some spelling variations:
during risk » using risk, during crises, during crisis
cost during » boost during, crust during, west during
gao ying » yao yang, fan ying, ran ying
ka ying » fan ying, ran ying, tan ying
ku ying » ku ring, hui ying, zhu ying
eu cost » au costa, der cost, end cost
how shu » how she, how shih, how slum

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: chen ((gao ying) OR (((ka ying) OR (ku ying)))) eu cost during risk how shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chen ((gao ying) or (((ka ying) OR (ku ying)))) eu cost during risk how shu ;~".
• Adding a wildcard symbol may retrieve word variants: chen ((gao ying) or (((ka ying) OR (ku ying)))) eu cost during risk how shu ;*.
