• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien anh) OR (thien thanh)) - hanh chinh ban dung cong dan ((khan cap) OR (thanh lap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien anh) OR (thien thanh)) - hanh chinh ban dung cong dan ((khan cap) or (thanh lap))*".
