• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chieu)) xanh - thanh tuong ca trong cong ((san chan) OR (san chay)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chieu)) xanh - thanh tuong ca trong cong ((san chan) OR (san chay)) cau*.
