Access the Algolia search service

Integrate the Algolia SearchBundle in your Symfony app to index, search, and manage data.

Use the SearchService to index, search, and manage data with Algolia.

Inject the SearchService using type hints

Symfony 4 ships with a lighter container that registers only core services. For search tasks, inject the SearchService into the constructor. Symfony takes care of instantiating the right implementation for you.

PHP

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Algolia\SearchBundle\SearchService;

class ExampleController extends AbstractController
{
    protected $searchService;

    public function __construct(SearchServiceInterface $searchService)
    {
        $this->searchService = $searchService;
    }
}

Access the SearchService from the container

Prefer injecting the SearchServiceInterface with type hints over retrieving it from the container. This approach follows Symfony best practices and improves testability.

Symfony 3 uses a container holding all public services, and services are public by default. This way, you can get the search.service from the container.

PHP

// In a container aware class
$searchService = $this->getContainer()->get('search.service');

// In a Symfony\Bundle\FrameworkBundle\Controller\Controller class
$searchService = $this->get('search.service');
