• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) y nang ((cho hoc) OR (khoa hoc)). hieu van cac xuc ban hanh vi cua cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) y nang ((cho hoc) or (khoa hoc)). hieu van cac xuc ban hanh vi cua cau*".
