3. Security/Authentication

You can connect to Elastic using Basic Authentication

<?php

use ElasticSearch\ElasticSearch;

class ExampleController extends Controller
{
    private $elastic;

    public function __construct()
    {
        $this->elastic = new ElasticSearch();

        $this->elastic->client()
                    ->basicAuth('user', 'password');
    }

    public function nested()
    {
        $nested = $this->elastic
                    ->nested()
                    ->index('my-index')
                    ->path('user')
                    ->params('size', 1)
                    ->addQuery('elastic.bool', function() {
                        return $this
                                ->must([
                                    [
                                        'match' => ['user.first' => 'Şero']
                                    ]
                                ])
                                ->getMap();
                    })
                    ->search();

        return $nested;
    }
}

You can set cloud id, hosts and api key

<?php

use ElasticSearch\ElasticSearch;

class ExampleController extends Controller
{
    private $elastic;

    public function __construct()
    {
        $this->elastic = new ElasticSearch();

        $hosts = [
            'http://localhost:9200'
        ];

        $this->elastic->client()
                    ->basicAuth('user', 'password')
                    ->hosts($hosts)
                    ->cloudId('cloud-id')
		    ->apiKey('enter-your-api-key')
	    	    ->sslVerification('path/to/cacert.pem');
    }

    public function multiMatch()
    {

        $search = $this->elastic->multiMatch()
                        ->index('my-index')
                        ->text('Şêro')
                        ->fuzziness(1)
                        ->fields(['text^3', 'name'])
                        ->search();

        return $search;
    }
}
