• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) y tang ma hoi. lieu va tham loc va danh ((vi cua) OR (di cua)) tre~.
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu sach)) y tang ma hoi. lieu va tham loc va danh ((vi cua) or (di cua)) tre*.
