• The words AND, OR and NOT may confuse the search; try adding quotes: "te mach hoc tap, nghien cuu cong hoc ((nhanh duong) OR (thanh duong)) hoc xa hoi van nhan van".
• Adding a wildcard symbol may retrieve word variants: te mach hoc tap, nghien cuu cong hoc ((nhanh duong) OR (thanh duong)) hoc xa hoi van nhan van*.
