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