• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ty lang) OR (ty hang)) xa hoi. hieu va cham xuc va phan lap ((dua tren) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ty lang) OR (ty hang)) xa hoi. hieu va cham xuc va phan lap ((dua tren) or (cuu tre))*".
