• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) nang x hoi. hieu va cham xuc ((van hanh) OR (van thanh)) vinh cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) nang x hoi. hieu va cham xuc ((van hanh) or (van thanh)) vinh cua tre*".
