• If you are trying to use Boolean operators, they must be ALL CAPS: ((((theo chieu) OR (ho chieu))) OR (thi hien)) xanh - dinh trong van thuong cong dan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((theo chieu) OR (ho chieu))) or (thi hien)) xanh - dinh trong van thuong cong dan toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((((theo chieu) OR (ho chieu))) or (thi hien)) xanh - dinh trong van thuong cong dan toan tap*.
