• If you are trying to use Boolean operators, they must be ALL CAPS: (((("chuong trinh cao ban va ca cay cong hoi viet nam") OR ((("chuong trinh co van va cao cay cong soi viet nam") OR ("chuong trinh cong van va cao cay cong soi viet nam"))))) OR ((("chuong trinh bao tran phan dau cac co oi viet nam") OR ("chuong trinh ban 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 hoi viet nam\") or (((\"chuong trinh co van va cao cay cong soi viet nam\") OR (\"chuong trinh cong van va cao cay cong soi viet nam\"))))) or (((\"chuong trinh bao tran phan dau cac co oi viet nam\") or (\"chuong trinh ban tran van chat cac co oi viet nam\"))))~".
• Removing quotes may allow a broader search: (((( chuong trinh cao ban va ca cay cong hoi viet nam ) or ((( chuong trinh co van va cao cay cong soi viet nam ) OR ( chuong trinh cong van va cao cay cong soi viet nam ))))) or ((( chuong trinh bao tran phan dau cac co oi viet nam ) or ( chuong trinh ban tran van chat cac co oi viet nam ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("chuong trinh cao ban va ca cay cong hoi viet nam") or ((("chuong trinh co van va cao cay cong soi viet nam") OR ("chuong trinh cong van va cao cay cong soi viet nam"))))) or ((("chuong trinh bao tran phan dau cac co oi viet nam") or ("chuong trinh ban tran van chat cac co oi viet nam"))))*.
