• If you are trying to use Boolean operators, they must be ALL CAPS: tu cach hoc tap, nghien cua toan hoc ((nganh khong) OR (nganh cong)) hoc xa hoi chu nhan dan~.
• Adding a wildcard symbol may retrieve word variants: tu cach hoc tap, nghien cua toan hoc ((nganh khong) or (nganh cong)) hoc xa hoi chu nhan dan*.
