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