映射器附件问题（Elasticsearch）

Question

我已经创建了mapper attachmet映射，如下所示。

PUT test-2016.06.11/person/_mapping
{
    "person" : {
        "properties" : {
            "file" : {
                "type" : "attachment",
                "fields" : {
                    "content" : {"store" : "yes"},
                    "title" : {"analyzer" : "chinese", "store" : "yes"},
                    "date" : {"store" : "yes"},
                    "author" : {"analyzer" : "chinese", "store" : "yes"},
                    "keywords" : {"analyzer" : "chinese","store" : "yes"},
                    "content_type" : {"store" : "yes"},
                    "content_length" : {"store" : "yes"},
                    "language" : {"analyzer" : "chinese", "store" : "yes"}
                }
            }
        }
    }
}

但是，当我查看放入索引的数据时，我看不到任何.raw字段。我应该如何更改我的映射以使kibana中的.raw字段成为可能？

提前致谢。
