• The words AND, OR and NOT may confuse the search; try adding quotes: "co sach hoi tap, nghien cuu dong luc nganh khong ((thuoc la) OR (thuoc tai)) hoi va nhan van~".
• Adding a wildcard symbol may retrieve word variants: co sach hoi tap, nghien cuu dong luc nganh khong ((thuoc la) OR (thuoc tai)) hoi va nhan van*.
