• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang cao hoa. hieu ve ((cham cuu) OR (chat cua)) van hanh ly ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang cao hoa. hieu ve ((cham cuu) or (chat cua)) van hanh ly ((cua tre) OR (cuu tre))".
