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