Perhaps you should try some spelling variations:
gender class » gender biases, gender bias
chain change » can change, champion change, chain channels
than change » can change, mean change, when change
gender lens » gender blind
robin paul » robyn paul, robbins paul, sabin paul
long i » long _, long 2, long a
mohan » johan

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: ((than change) OR (chain change)) long i ((gender lens) OR (gender class)) mohan robin paul ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((than change) or (chain change)) long i ((gender lens) OR (gender class)) mohan robin paul ;~".
• Adding a wildcard symbol may retrieve word variants: ((than change) or (chain change)) long i ((gender lens) OR (gender class)) mohan robin paul ;*.
