• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach hoc tap, nghien ((cuu tinh) OR (cuu cong)) hoc nhanh hung hoc xa hoi va nhan van~.
• Adding a wildcard symbol may retrieve word variants: tu sach hoc tap, nghien ((cuu tinh) or (cuu cong)) hoc nhanh hung hoc xa hoi va nhan van*.
