• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chau) OR (theo phap)) tinh - hanh trang luan trinh cong dan ((toan tai) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chau) OR (theo phap)) tinh - hanh trang luan trinh cong dan ((toan tai) or (toan cao))*".
