• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu sach)) - hanh chinh ((cua khong) OR (hua khong)) cang san tranh luan*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu sach)) - hanh chinh ((cua khong) OR (hua khong)) cang san tranh luan*".
