• If you are trying to use Boolean operators, they must be ALL CAPS: ((((hoc hien) OR (hoc thieu))) OR (ho chieu)) xanh - hanh trang cua nhung cong van toan cau~.
• Adding a wildcard symbol may retrieve word variants: ((((hoc hien) or (hoc thieu))) or (ho chieu)) xanh - hanh trang cua nhung cong van toan cau*.
