• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("cong trinh cao van va cac cay co loi viet nam") OR ("cong trinh cao van va cac cam co loi viet nam"))) OR ((("cong trinh cao lanh van cac cay co oi viet nam") OR ("cong trinh cao lanh van hac cay co oi viet nam"))))) OR ("cong trinh cao tang van cac cay cong soi viet nam")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"cong trinh cao van va cac cay co loi viet nam\") or (\"cong trinh cao van va cac cam co loi viet nam\"))) or (((\"cong trinh cao lanh van cac cay co oi viet nam\") OR (\"cong trinh cao lanh van hac cay co oi viet nam\"))))) or (\"cong trinh cao tang van cac cay cong soi viet nam\"))".
