• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((ty chang) OR (ty hang)) xu hoi. hieu ve cam luc ban hanh phan ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((ty chang) OR (ty hang)) xu hoi. hieu ve cam luc ban hanh phan ((cua tre) or (cuu tre))*".
