• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang ma hoi. hieu ve chat duc van ((((thanh loi) OR (thanh hoa))) OR (hanh tai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang ma hoi. hieu ve chat duc van ((((thanh loi) OR (thanh hoa))) or (hanh tai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang ma hoi. hieu ve chat duc van ((((thanh loi) OR (thanh hoa))) or (hanh tai)) cua tre*.
