• If you are trying to use Boolean operators, they must be ALL CAPS: cao ((dieu tinh) OR (diep tinh)) - thanh tuong va nhung cong san ((toan tai) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cao ((dieu tinh) OR (diep tinh)) - thanh tuong va nhung cong san ((toan tai) or (toan tap))*".
