Perhaps you should try some spelling variations:
women's labour » women's labor
labour health » labor health, about health, laborers health
health gains » health gain, health gaps, health goals
can women's » ghana women's
wang liang » wang yang
yan liang » yang liang, you liang, yan wang
yang jui » yang judy, yang di, yang xi
chang ha » chang mae

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: can women's labour health gains ((((yan liang) OR (wang liang))) OR (yang jui)) chang ha ;~.
• Adding a wildcard symbol may retrieve word variants: can women's labour health gains ((((yan liang) or (wang liang))) or (yang jui)) chang ha ;*.
