elasticsearch - Elasticsearch:禁用索引编制，但将copy_to应用于字段

Question

我正在尝试将字段仅用于复制目的，而不是使用下面的映射对其进行索引

        "Line2": {
            "type":     "text",
            "copy_to": "AllFields" ,
            "enabled": false
        }

但是得到异常(exception)

{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"Mapping definition for [Line2] has unsupported parameters: [enabled : false]"}],"type":"mapper_parsing_exception","reason":"Failed to parse mapping [_doc]: Mapping definition for [Line2] has unsupported parameters: [enabled : false]","caused_by":{"type":"mapper_parsing_exception","reason":"Mapping definition for [Line2] has unsupported parameters: [enabled : false]"}},"status":400}

能做到吗？

ES版本:6.7

如果您不想索引(使之可搜索)一个字段，请对该字段使用"index": false。

"Line2": {
    "type": "text",
    "copy_to": "AllFields",
    "index": false
  }
