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