• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu tinh)) - anh trong ((van dung) OR (tin dung)) cong thanh van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu tinh)) - anh trong ((van dung) OR (tin dung)) cong thanh van ban".
