• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (theo tieu)) sang - hanh tang van nhung cong ((van tai) OR (van thanh)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (theo tieu)) sang - hanh tang van nhung cong ((van tai) or (van thanh)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (theo tieu)) sang - hanh tang van nhung cong ((van tai) or (van thanh)) cau*.
