• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien anh) OR (chieu xanh)) - canh manh cua ((thong duong) OR (tuong duong)) dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien anh) or (chieu xanh)) - canh manh cua ((thong duong) OR (tuong duong)) dan than cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((thien anh) or (chieu xanh)) - canh manh cua ((thong duong) OR (tuong duong)) dan than cau*.
