• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (hoc sach)) kho tang van hoi. hieu va cam duc va thanh ((toan cua) OR (tan cua)) vat*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (hoc sach)) kho tang van hoi. hieu va cam duc va thanh ((toan cua) OR (tan cua)) vat*".
