• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach kho tang van hoa. hieu van cau xuc van ((doanh vang) OR (doanh van)) cua tu~".
• Adding a wildcard symbol may retrieve word variants: tu sach kho tang van hoa. hieu van cau xuc van ((doanh vang) OR (doanh van)) cua tu*.
