Elasticsearch-PHP reindex未按预期工作

Question

reindex接口文档：https://www.elastic.co/guide/en/elasticsearch/client/php-api/6.0/ElasticsearchPHP_Endpoints.html#Elasticsearch_Clientreindex_reindex

/*
$params['refresh']             = (boolean) Should the effected indexes be refreshed?
       ['timeout']             = (time) Time each individual bulk request should wait for shards that are unavailable
       ['consistency']         = (enum) Explicit write consistency setting for the operation
       ['wait_for_completion'] = (boolean) Should the request should block until the reindex is complete
       ['requests_per_second'] = (float) The throttle for this request in sub-requests per second. 0 means set no throttle
       ['body']                = (array) The search definition using the Query DSL and the prototype for the index request (Required)
       ['body']  = (array) Request body
*/

$params = [
    // ...
];

$client = ClientBuilder::create()->build();
$response = $client->reindex($params);

Elasticsearch版本为5.6.13。

我试图使用上面PHP客户端的reindex API将源索引重新索引到目标索引。sourceIndex只有1个文档。

请求：

$params = [
    'body' => [
        'source' => [
            'index'  => 'sourceIndex',
        ],
        'dest' => [
            'index' => 'destIndex'
        ]
    ]
];
$response = $client->reindex($params);

响应：

(
    [took] => 2
    [timed_out] =>
    [total] => 0
    [updated] => 0
    [created] => 0
    [deleted] => 0
    [batches] => 0
    [version_conflicts] => 0
    [noops] => 0
    [retries] => Array
        (
            [bulk] => 0
            [search] => 0
        )

    [throttled_millis] => 0
    [requests_per_second] => -1
    [throttled_until_millis] => 0
    [failures] => Array
        (
        )

)

如您所见，重新索引的文档是0(总=>为0)。

使用Kibana的DevTool可以很好地工作，但使用elasticsearch-php客户端就不行了。

POST _reindex
{
  "source": {
    "index": "sourceIndex"
  },
  "dest": {
    "index": "destIndex"
  }
}

任何帮助都是非常感谢的。如果你需要更多细节来帮助回答这个问题，请让我知道。

仅供参考-以防有人碰巧面临同样的问题。问题是源索引的refresh_interval设置为-1。要使reindex操作生效，只需在调用_reindex接口之前刷新源索引即可。
