• If you are trying to use Boolean operators, they must be ALL CAPS: dong hoang fan ((((data chen) OR (data coe))) OR (data chi)) yang mind how shih ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong hoang fan ((((data chen) OR (data coe))) or (data chi)) yang mind how shih ;*".
