• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (thi chieu)) xanh - thanh tung cua dung cong ((hang hang) OR (nang hang)) dau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (thi chieu)) xanh - thanh tung cua dung cong ((hang hang) OR (nang hang)) dau*.
