+To run the above examples by injecting the service instead of passing the container (the preferred way in Symfony 4), add the following to the constructor, and replace the `$this->container` calls with `$this->sphinx`, `$this->em`, etc.
+
+```php
+use Javer\SphinxBundle\Sphinx\Manager;
+use Knp\Component\Pager\Pagination\PaginationInterface;
+use Doctrine\ORM\EntityManagerInterface;
+
+private $sphinx;
+private $em;
+private $paginator;
+

+public function __construct(EntityManagerInterface $em,
