• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach y lang van hoi. hieu van cac tuc va nhanh thai ((cua tre) OR (((va triet) OR (ve triet))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach y lang van hoi. hieu van cac tuc va nhanh thai ((cua tre) or (((va triet) OR (ve triet))))*".
