• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ky lang van hoi. hieu ve cac ((((duc van) OR (duc va))) OR (duc manh)) hanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ky lang van hoi. hieu ve cac ((((duc van) OR (duc va))) or (duc manh)) hanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: so sanh ky lang van hoi. hieu ve cac ((((duc van) OR (duc va))) or (duc manh)) hanh vai cua tre*.
