• If you are trying to use Boolean operators, they must be ALL CAPS: (((("chuong trinh cao ban va ca cay cong scuoi viet nam") OR ((("chuong trinh co van va cao cay cong soi viet nam") OR ("chuong trinh co van va cao cay cong shoi viet nam"))))) OR ((("chuong trinh bao tran van cau cac co oi viet nam") OR ("chuong trinh bay tran van chat cac co oi viet nam"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"chuong trinh cao ban va ca cay cong scuoi viet nam\") or (((\"chuong trinh co van va cao cay cong soi viet nam\") OR (\"chuong trinh co van va cao cay cong shoi viet nam\"))))) or (((\"chuong trinh bao tran van cau cac co oi viet nam\") or (\"chuong trinh bay tran van chat cac co oi viet nam\"))))~".
• Removing quotes may allow a broader search: (((( chuong trinh cao ban va ca cay cong scuoi viet nam ) or ((( chuong trinh co van va cao cay cong soi viet nam ) OR ( chuong trinh co van va cao cay cong shoi viet nam ))))) or ((( chuong trinh bao tran van cau cac co oi viet nam ) or ( chuong trinh bay tran van chat cac co oi viet nam ))))~.
