Perhaps you should try some spelling variations:
credit during » credit scoring, credit rating
exit during » mexico during
liang ying » liang liying, huang ying, zhang ying
crises how » crisis how
fang ying » fan ying, huang ying, zhang ying
how race » how space
cai » cabi

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: cai ((fang ying) OR (liang ying)) jin ((exit during) OR (credit during)) crises how race ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cai ((fang ying) OR (liang ying)) jin ((exit during) or (credit during)) crises how race ;~".
• Adding a wildcard symbol may retrieve word variants: cai ((fang ying) OR (liang ying)) jin ((exit during) or (credit during)) crises how race ;*.
