• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu sach) OR (vien nganh)) - manh trung ((cua nang) OR (chua nang)) song van ban cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu sach) or (vien nganh)) - manh trung ((cua nang) OR (chua nang)) song van ban cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sach) or (vien nganh)) - manh trung ((cua nang) OR (chua nang)) song van ban cau*.
