Elasticsearch多附件上传

Question

我正在尝试使用elasticsearch（版本2.33）在文件中查找字符串， 我试图创建映射来存储多个文件，但它总是给我相同的错误， 这是我到目前为止所做的：

PUT /消息

PUT / messages / attachment / _mapping

DATA：

{
    "attachment": {
        "properties": {
            "my_attachment": {
                "type": "nested",
                "include_in_parent": true,
                "properties": {
                    "attachmentContent": {
                        "type": "attachment",
                        "path": "full",
                        "fields": {
                            "attachmentContent": {
                                "type": "string",
                                "term_vector": "with_positions_offsets",
                                "store": true
                            }
                        }
                    },
                    "path": {
                        "type": "string"
                    },
                    "attachment_id": {
                        "type": "integer"
                    }
                }
            }
        }
    }
}

总是给我同样的错误：

{
  "error": {
    "root_cause": [
      {
        "type": "mapper_parsing_exception",
        "reason": "Mapping definition for [fields] has unsupported parameters:  [attachmentContent : {type=string}]"
      }
    ],
    "type": "mapper_parsing_exception",
    "reason": "Mapping definition for [fields] has unsupported parameters:  [attachmentContent : {type=string}]"
  },
  "status": 400
}

尝试按照评论中的说明进行操作 http://grokbase.com/t/gg/elasticsearch/148v29ymaf/how-can-we-index-array-of-attachments 并且它无法正常工作

感谢任何帮助，Nevo：）
