• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) tay lang xa hoi. hieu ve cau luc va hanh ((vi cua) OR (de cua)) te~.
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu sach)) tay lang xa hoi. hieu ve cau luc va hanh ((vi cua) or (de cua)) te*.
