• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sach y)) nang ((ho hoi) OR (hoc hoi)). hieu ve cac duc van anh thai cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (sach y)) nang ((ho hoi) OR (hoc hoi)). hieu ve cac duc van anh thai cua tre*.
