• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sach thu ((hang co) OR (((hang cho) OR (phong cho)))) hoi. hieu va cao xu va hanh vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sach thu ((hang co) or (((hang cho) OR (phong cho)))) hoi. hieu va cao xu va hanh vi cuu tre*".
