• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu sach) OR (chieu tinh)) - hanh trung phai ((nhuong cong) OR (luong cong)) ban than cau.
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sach) or (chieu tinh)) - hanh trung phai ((nhuong cong) or (luong cong)) ban than cau*.
