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