• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((thanh trung) OR (thanh tung)) tuan dang cong dan ((phan cac) OR (phan dau))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((thanh trung) OR (thanh tung)) tuan dang cong dan ((phan cac) or (phan dau))*".
