• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu nang ((ma hoi) OR (ma hoa)). lieu va cac xuc ban thanh vi ((cua viet) OR (cua vat))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu nang ((ma hoi) OR (ma hoa)). lieu va cac xuc ban thanh vi ((cua viet) or (cua vat))*".
