• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (thien anh)) - ((than tinh) OR (thai tinh)) cao thuong cong manh toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (thien anh)) - ((than tinh) OR (thai tinh)) cao thuong cong manh toan tap*".
