• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo hieu) OR (thien hieu)) lang - anh mang cua hang ((cong san) OR (cong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo hieu) OR (thien hieu)) lang - anh mang cua hang ((cong san) or (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo hieu) OR (thien hieu)) lang - anh mang cua hang ((cong san) or (cong tan)) toan cau*.
