• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang ((((ha hoi) OR (hoa hoi))) OR (ha noi)). lieu va cam tuc va thanh van cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang ((((ha hoi) OR (hoa hoi))) or (ha noi)). lieu va cam tuc va thanh van cua tre*".
