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