• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((tthanh trung) OR (thanh trung)) thuat nhung cong san ((thanh cac) OR (hanh cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((tthanh trung) or (thanh trung)) thuat nhung cong san ((thanh cac) OR (hanh cac))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((tthanh trung) or (thanh trung)) thuat nhung cong san ((thanh cac) OR (hanh cac))*.
