通常ElasticSearch文档存储为:

{      
    "_index": "some_index",
    "_type": "some_type",
    "_id": "blah_blah",
    "_score": null,
    "_source": {
        "field_a" : "value_a",
        "field_b" : "value_b"
        ........
}

在查询数据时是否可以在_source本身中包含_id？例如

{
    "_index": "some_index",
    "_type": "some_type",
    "_id": "blah_blah",
    "_score": null,
    "_source": {
        "_id": "blah_blah", // Added in the _source object
        "field_a" : "value_a",
        "field_b" : "value_b"
        ........
}

假设我无法控制我正在编写的数据,因此无法将其插入源代码中.此外,我可以读取整个对象并手动包含它,但想知道是否有办法通过ES查询这样做.
