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