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