• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((((hanh trang) OR (minh trang))) OR (thanh trung)) cua bang cong tan tran chau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((((hanh trang) OR (minh trang))) or (thanh trung)) cua bang cong tan tran chau*".
