ES之文档修改及删除（入门）

一、全量覆盖
原id为1001的数据内容为：

{
    "_index": "test-index-3",
    "_type": "_doc",
    "_id": "1001",
    "_version": 3,
    "_seq_no": 5,
    "_primary_term": 1,
    "found": true,
    "_source": {
        "title": "test",
        "num": 1,
        "date": "20211213"
    }
}

发送【POST】或【PUT】请求：http://127.0.0.1:9200/test-index-3/_doc/1001，参数如下

{
    "test":"abc"
}

执行后返回结果为

{
    "_index": "test-index-3",
    "_type": "_doc",
    "_id": "1001",
    "_version": 4,
    "result": "updated",
    "_shards": {
        "total": 2,
        "successful": 1,
        "failed": 0
    },
    "_seq_no": 13,
    "_primary_term": 1
}

修改后查询结果为

{
    "_index": "test-index-3",
    "_type": "_doc",
    "_id": "1001",
    "_version": 4,
    "_seq_no": 13,
    "_primary_term": 1,
    "found": true,
    "_source": {
        "test": "abc"
    }
}

二、修改某个字段
原id为1002的数据内容为：

{
    "_index": "test-index-3",
    "_type": "_doc",
    "_id": "1002",
    "_version": 2,
    "_seq_no": 7,
    "_primary_term": 1,
    "found": true,
    "_source": {
        "title": "test",
        "num": 1,
        "date": "20211213"
    }
}

发送【POST】请求：http://127.0.0.1:9200/test-index-3/_update/1002，参数如下（不能用PUT协议，如果参数中有新字段，则会新增字段）

{
    "doc" : {
        "title" : "测试",
        "file": 666
    }
}

执行后返回结果为

{
    "_index": "test-index-3",
    "_type": "_doc",
    "_id": "1002",
    "_version": 3,
    "result": "updated",
    "_shards": {
        "total": 2,
        "successful": 1,
        "failed": 0
    },
    "_seq_no": 15,
    "_primary_term": 1
}

修改后查询结果为

{
    "_index": "test-index-3",
    "_type": "_doc",
    "_id": "1002",
    "_version": 3,
    "_seq_no": 15,
    "_primary_term": 1,
    "found": true,
    "_source": {
        "title": "测试",
        "num": 1,
        "date": "20211213",
        "file": 666
    }
}

三、删除数据
发送【DELETE】请求：http://127.0.0.1:9200/test-index-3/_doc/1001
结果返回如下

{
    "_index": "test-index-3",
    "_type": "_doc",
    "_id": "1001",
    "_version": 6,
    "result": "deleted",
    "_shards": {
        "total": 2,
        "successful": 1,
        "failed": 0
    },
    "_seq_no": 18,
    "_primary_term": 1
}
