Perhaps you should try some spelling variations:
gender class » gender biases, gender bias
gender laws » gender law, gendered laws, gender lens
yang chun » tang chun, wang chun, kang chen
take bane » take based, take care, take back
bane paul » bance paul, lange paul, cape paul
yang jun » yang jui, pang jun, yang jin

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 chun) OR (yang jun)) 3 ((gender laws) OR (gender class)) take bane paul ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang chun) or (yang jun)) 3 ((gender laws) OR (gender class)) take bane paul ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang chun) or (yang jun)) 3 ((gender laws) OR (gender class)) take bane paul ;*.
