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