• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - ((hanh tran) OR (hanh trang)) quang tong cong ((thanh toan) OR (anh tuan)) cau~.
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - ((hanh tran) or (hanh trang)) quang tong cong ((thanh toan) or (anh tuan)) cau*.
