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