• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (hoc hien)) anh - hanh tranh cua dang cong ((dan toan) OR (manh toan)) ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (hoc hien)) anh - hanh tranh cua dang cong ((dan toan) OR (manh toan)) ban*".
