• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (hien hanh)) - ((hanh mang) OR (anh tang)) cua nhung cong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (hien hanh)) - ((hanh mang) or (anh tang)) cua nhung cong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) OR (hien hanh)) - ((hanh mang) or (anh tang)) cua nhung cong tan toan cau*.
