• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("cong trinh co lan va cao cay co hoi viet nam") OR ("cong trinh co lanh va cao cay co hoi viet nam"))) OR ("cong trinh co lan va tao cay co loi viet nam"))) OR ((("cong trinh cao lan va cac tac co soi viet nam") OR ("cong trinh cao van va cac tac co soi viet nam"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"cong trinh co lan va cao cay co hoi viet nam\") OR (\"cong trinh co lanh va cao cay co hoi viet nam\"))) or (\"cong trinh co lan va tao cay co loi viet nam\"))) or (((\"cong trinh cao lan va cac tac co soi viet nam\") or (\"cong trinh cao van va cac tac co soi viet nam\"))))*".
• Removing quotes may allow a broader search: (((((( cong trinh co lan va cao cay co hoi viet nam ) OR ( cong trinh co lanh va cao cay co hoi viet nam ))) or ( cong trinh co lan va tao cay co loi viet nam ))) or ((( cong trinh cao lan va cac tac co soi viet nam ) or ( cong trinh cao van va cac tac co soi viet nam ))))*.
