How to bulk delete docs from elasticsearch using php

Question

I am having the following code to delete the docs from elasticsearch .

public function deleteByQuery(){

    $client = $this->_connectElasticSearchClient();
    $params = [
       'index' => $this->_indexName,
       'type' => $this->_typeName,
       'body' => [
           'query' => [
               'match' => [
                   'brand' => 'apple'
               ]
           ]
       ]
    ];
    $response = $client->deleteByQuery($params);
    print_r($response);die;
 }

I am getting the following as response.

{
  "found": false,
  "_index": "gadgets",
  "_type": "products",
  "_id": "_query",
  "_version": 1,
  "_shards": {
    "total": 1,
    "successful": 1,
    "failed": 0
  }
}

Tried changing the query string and all.but no use. While searching with the above query ,I am getting data also.

I am using Elasticsearch-PHP Client.

Since you're using Elasticsearch 2.1, you need to know that the delete-by-query feature has been removed from the core and moved into a dedicated plugin .

You need to install that plugin first in order for your PHP code to work.

./bin/plugin install delete-by-query
