• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chau) OR (theo chieu)) tinh - hanh trung xuan trung ((trung dan) OR (trung dai)) van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chau) or (theo chieu)) tinh - hanh trung xuan trung ((trung dan) OR (trung dai)) van ban*".
