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