• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang x hoi. hieu ((va cam) OR (va cac)) xuc va dang vinh ((cu treo) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang x hoi. hieu ((va cam) or (va cac)) xuc va dang vinh ((cu treo) OR (cau tren))".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang x hoi. hieu ((va cam) or (va cac)) xuc va dang vinh ((cu treo) OR (cau tren))*.
