• If you are trying to use Boolean operators, they must be ALL CAPS: tu mach hoc tap, nghien cuu mon hoc nganh thong hoa ma hoi va ((thanh van) OR (nhan dan))~.
• Adding a wildcard symbol may retrieve word variants: tu mach hoc tap, nghien cuu mon hoc nganh thong hoa ma hoi va ((thanh van) or (nhan dan))*.
