Perhaps you should try some spelling variations:
bhutan gender » human gender, rhoton gender
gender task » gender talk, gendered task, gender case
min hyoung » min hong, mun young
hyoung gun » young eun
yang yang » wang yang, wang yan
yang jui » yang judy, yang xi, yang yi
3 bhutan » _ bhutan, 3.2 bhutan, 16 bhutan
task min » task cil, task ii
nr 3 » nr 1, nr 2, nr 4

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: ((((yang yang) OR (yang jui))) OR (yang di))nr 3 bhutan gender task min hyoung gun ;~.
• Adding a wildcard symbol may retrieve word variants: ((((yang yang) or (yang jui))) or (yang di))nr 3 bhutan gender task min hyoung gun ;*.
