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