• If you are trying to use Boolean operators, they must be ALL CAPS: wang wang yan chan kang ((((yong jui) OR (yang jun))) OR (yong cai)) kang han ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang yan chan kang ((((yong jui) OR (yang jun))) or (yong cai)) kang han ;*".
