• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ((y nang) OR (v nang)) xa hoi. hieu va cac xuc ban hang vi cua viet~.
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) ((y nang) or (v nang)) xa hoi. hieu va cac xuc ban hang vi cua viet*.
