• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing yuan) OR (wang yuhan)) wang hoong chang chen hui ((hong ghi) OR (hong (tan OR than))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing yuan) OR (wang yuhan)) wang hoong chang chen hui ((hong ghi) or (hong (tan or than))) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing yuan) OR (wang yuhan)) wang hoong chang chen hui ((hong ghi) or (hong (tan or than))) ;*.
