• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chu) OR (ho chieu)) tinh - hanh trang cua thong cong ((van toan) OR (van tan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) or (ho chieu)) tinh - hanh trang cua thong cong ((van toan) OR (van tan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) or (ho chieu)) tinh - hanh trang cua thong cong ((van toan) OR (van tan)) cau*.
