• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu anh) OR (thien danh)) - hanh tranh ((cac thuong) OR (cac truong)) cong lang toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu anh) or (thien danh)) - hanh tranh ((cac thuong) OR (cac truong)) cong lang toan cau*".
