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