Perhaps you should try some spelling variations:
during crisis » during crises, housing crisis
debat during » debate during, debt during, exit during
jie debat » le debat
how space » how race
fan yang » fan ying, wang yang, yang yang
tan yang » tan ying, tan yong, tao yang
dan yang » daun yang, wang yang, yang yang

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: wai ((((fan yang) OR (tan yang))) OR (dan yang)) jie debat during crisis how space ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai ((((fan yang) OR (tan yang))) or (dan yang)) jie debat during crisis how space ;~".
• Adding a wildcard symbol may retrieve word variants: wai ((((fan yang) OR (tan yang))) or (dan yang)) jie debat during crisis how space ;*.
