• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing tan) OR (hong tan)) ((((yang yue) OR (wang yan))) OR (yang jun)) cheng zhang wei wong sam ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing tan) OR (hong tan)) ((((yang yue) or (wang yan))) or (yang jun)) cheng zhang wei wong sam ;*".
