yuan chang » yuan cheng, huang chang, han chang
liang zhu » liang zhi, ying zhu, jing zhu
gene more » one more, gene meme, gene one
than wong » thang long, than one, than done
yang zhi » wang zhi, yan zhi, liang zhi
wong sau » wong sam, wong siu, wong shiu

• If you are trying to use Boolean operators, they must be ALL CAPS: yuan chang ((yang zhi) OR (liang zhu)) gene more than wong sau ;*.
