• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty nang) OR (ty xang)) doc loi. hieu va cham xuc ((va thanh) OR (ban thanh)) lai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty nang) OR (ty xang)) doc loi. hieu va cham xuc ((va thanh) or (ban thanh)) lai cua tre*".
