• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((kang han) OR (kang chen)) run dan yang jin ((kong a) OR (kong yam)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((kang han) OR (kang chen)) run dan yang jin ((kong a) or (kong yam)) ;*".
