• If you are trying to use Boolean operators, they must be ALL CAPS: thu cach hoc tap, nghien ((cuu toan) OR (huu toan)) hoc nganh thong hoc bai khoi va nhan van~.
• Adding a wildcard symbol may retrieve word variants: thu cach hoc tap, nghien ((cuu toan) or (huu toan)) hoc nganh thong hoc bai khoi va nhan van*.
