• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (ho chieu)) xanh - hanh trinh cua thong ((cong van) OR (cong san)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (ho chieu)) xanh - hanh trinh cua thong ((cong van) OR (cong san)) toan cao*.
