• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ((ty nang) OR (ty xang)) xa hoi. hieu va cam tuc va anh va cua te~.
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu sach)) ((ty nang) or (ty xang)) xa hoi. hieu va cam tuc va anh va cua te*.
