• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cach thoi dai, nghien cuu cong hoc nhanh chuong hoc ma hoi ((van nhan) OR (van thanh)) va~".
• Adding a wildcard symbol may retrieve word variants: tu cach thoi dai, nghien cuu cong hoc nhanh chuong hoc ma hoi ((van nhan) OR (van thanh)) va*.
