• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - canh tranh cua truong ((((tuong dan) OR (xuong dan))) OR (dung san)) toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - canh tranh cua truong ((((tuong dan) OR (xuong dan))) or (dung san)) toan cau*".
