• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang x hoi. hieu ve ((chat duc) OR (chat xuc)) van ((thanh loi) OR (hanh tai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang x hoi. hieu ve ((chat duc) OR (chat xuc)) van ((thanh loi) or (hanh tai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang x hoi. hieu ve ((chat duc) OR (chat xuc)) van ((thanh loi) or (hanh tai)) cua tre*.
