• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach _ sang ma hoi. lieu ((va tham) OR (va cham)) loc va danh ((vi cua) OR (dai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach _ sang ma hoi. lieu ((va tham) OR (va cham)) loc va danh ((vi cua) or (dai cua)) tre*".
