ren yang » ren yan, chen yang, dan yang
wong sam » wong sau, wong lai, kong sar

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang kyoung) OR (wang yong)) wang zhi ren yang ji ((wong sam) OR (union sacu)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang kyoung) OR (wang yong)) wang zhi ren yang ji ((wong sam) or (union sacu)) ;*".
