Create an indexedit

Now that we are starting fresh (no data or index), let’s add a new index with some custom settings:

$params = [
    'index' => 'my_index',
    'body' => [
        'settings' => [
            'number_of_shards' => 2,
            'number_of_replicas' => 0
        ]
    ]
];

$response = $client->indices()->create($params);
print_r($response);

Elasticsearch will now create that index with your chosen settings, and return an acknowledgement:

Array
(
    [acknowledged] => 1
)
