• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((((lang xa) OR (dang xay))) OR (tang van)) hoi. hieu van lam xuc va tinh lao cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((((lang xa) OR (dang xay))) or (tang van)) hoi. hieu van lam xuc va tinh lao cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((((lang xa) OR (dang xay))) or (tang van)) hoi. hieu van lam xuc va tinh lao cua tre*.
