• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (hoc hien)) hach - canh doanh cua nhung cong ((dan than) OR (van than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (hoc hien)) hach - canh doanh cua nhung cong ((dan than) OR (van than)) cau*.
