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