Perhaps you should try some spelling variations:
credit during » credit scoring, credit rating
cost during » boost during, crust during, west during
exit during » mexico during
wang yang » wang yan, wang liang, wang yanling
yang sang » yang yang, yang guang, yang liang
sang minh » kang minah, anh minh, song min
risk cong » risk coping, risk among, risk along

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 sang minh ((cost during) OR (((credit during) OR (exit during)))) risk cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang sang minh ((cost during) or (((credit during) OR (exit during)))) risk cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang sang minh ((cost during) or (((credit during) OR (exit during)))) risk cong shu ;*.
