• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chieu)) xanh - ((lanh manh) OR (lan anh)) cua nhung cong tan phan dau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chieu)) xanh - ((lanh manh) OR (lan anh)) cua nhung cong tan phan dau*.
