php - Elasticsearch 部分批量更新

Question

我有 6k 的数据要在 ElasticSearch 中更新。而且我必须使用 PHP。 我在文档中搜索并找到了这个，Bulk Indexing但这并没有保留以前的数据。

我有结构:

[
  {
    'name': 'Jonatahn',
    'age' : 21
  }
]

我要更新的代码片段:

$params =[
    "index" => "customer",
    "type" => "doc",
    "body" => [
        [
            "index" => [
                "_index" => "customer",
                "_type" => "doc",
                "_id" => "09310451939"
            ]
        ],
        [
            "name" => "Jonathan"
        ]
    ]
];

$client->bulk($params);

当我发送 ['name' => 'Jonathan'] 时，我希望 name 会更新并保持 age，但是age 被删除。 当然，我仍然可以逐个更新数据，但这需要很长时间，有没有更好的方法来做到这一点？

我的错误是使用"index"，但正确的方法是"update"。

最终代码为:

$params =[
"index" => "customer",
"type" => "doc",
"body" => [
    [
        "update" => [
    //   ^^^^^^ Here I change from index to update
            "_index" => "customer",
            "_type" => "doc",
            "_id" => "09310451939"
        ]
    ],
    [
        "doc" => [
            "name" => "Jonathan"
        ]
    ]
]
];

$client->bulk($params);

使用上面的代码，我的数据保留了以前的数据，只是更新了我传入的参数。

                                    [age] => 23
                                )

                        )

                )

        )
