• If you are trying to use Boolean operators, they must be ALL CAPS: theo tieu xanh - ((thanh dung) OR (thanh tung)) cua dong cong tan ((toan cao) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - ((thanh dung) OR (thanh tung)) cua dong cong tan ((toan cao) or (toan ban))*".
