• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty sang ((ma hoa) OR (xa hoi)). hieu ve cac xuc van hanh ((thai cua) OR (than cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty sang ((ma hoa) or (xa hoi)). hieu ve cac xuc van hanh ((thai cua) OR (than cua)) tre".
