Perhaps you should try some spelling variations:
jeang yean » jeong yeon
yan yang » yang yang, yao yang, dan yang
law main » law pain, law making, law made
new main » new spain, new math
ai test » api test, i test, ein test
ii test » i test, api test, ii texts
wang » wing, wan, lang

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 yan yang ((ai test) OR (ii test)) ((law main) OR (new main)) jeang yean ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan yang ((ai test) or (ii test)) ((law main) or (new main)) jeang yean ;*.
