Quick Start
The SearchService
is your entry point for any operation with the Algolia engine:
- Index data
- Search
- Clear data
Retrieving the SearchService
Type-hinting
Symfony 4 ships with a lighter container, where only core services are registered. If your controller will be responsible for search-related tasks, you can inject the SearchService
into the constructor by type-hinting the SearchServiceInterface
. Symfony will take care of instantiating the right implementation for you.

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;
}
}
Directly from the container
Symfony 3 uses a container holding all public services, and services are public by default. This way, you can easily get the search.service
from the container.
Be aware however that it’s not considered a best practice by Symfony. We recommend using type-hinting to retrieve the SearchService
.

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