• If you are trying to use Boolean operators, they must be ALL CAPS: te cach hoc tap, nghien cuu cong ((hoc doanh) OR (hoc dan)) khoa hoc mai khoi van nhan van~.
• Adding a wildcard symbol may retrieve word variants: te cach hoc tap, nghien cuu cong ((hoc doanh) or (hoc dan)) khoa hoc mai khoi van nhan van*.
