• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (theo chu)) xanh - canh tinh ban hang cong manh ((toan cau) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (theo chu)) xanh - canh tinh ban hang cong manh ((toan cau) OR (toan cao))*".
