• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky ((lang xa) OR (((dang xay) OR (dang van)))) hoi. hieu van cam xuc va dan dinh cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky ((lang xa) or (((dang xay) OR (dang van)))) hoi. hieu van cam xuc va dan dinh cau treo*".
