yang jin » yang jie, yang jun, ying jin
jin kang » jin chang, jin kyung, jing fang

• If you are trying to use Boolean operators, they must be ALL CAPS: ((liang sun) OR (wang yidan)) yun yu wang yang jin kang (hai OR hadi) ;~.
• Adding a wildcard symbol may retrieve word variants: ((liang sun) or (wang yidan)) yun yu wang yang jin kang (hai or hadi) ;*.
