• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu sach - manh trung cua nhung cong san ((((tran cao) OR (tran chau))) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu sach - manh trung cua nhung cong san ((((tran cao) OR (tran chau))) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo chu sach - manh trung cua nhung cong san ((((tran cao) OR (tran chau))) or (toan cao))*.
