chuang hui » chun hui, zhang hui
yang boon » ong boon
wing dan » king dan, wang dan, wing ian

• If you are trying to use Boolean operators, they must be ALL CAPS: wing dan yang boon chong chuang hui ((hong ghi) OR (hong (tan OR than))) ;~.
• Adding a wildcard symbol may retrieve word variants: wing dan yang boon chong chuang hui ((hong ghi) or (hong (tan or than))) ;*.
