Perhaps you should try some spelling variations:
credit during » credit scoring, credit rating
crises china » crisis china's, classes china, crises asia
exit during » mexico during
yang dewan » yang dean, wang dewen
wang yang » wang yan, wang yanling
china saw » china sea, china si, china sub

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) OR (wang liang)) yang dewan ((exit during) OR (credit during)) crises china saw ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) OR (wang liang)) yang dewan ((exit during) or (credit during)) crises china saw ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) OR (wang liang)) yang dewan ((exit during) or (credit during)) crises china saw ;*.
