• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (doi chi)) sach - hanh trang cua dung phuong ((dan than) OR (manh toan)) cau~.
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (doi chi)) sach - hanh trang cua dung phuong ((dan than) or (manh toan)) cau*.
