This question is quite old and you probably found a solution already but since I got here through Google search and know an answer I will contribute.

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\JsonResponse;
use FOS\RestBundle\Request\ParamFetcher;
use FOS\RestBundle\Controller\Annotations\QueryParam;
use Nelmio\ApiDocBundle\Annotation\ApiDoc;

class DefaultController extends Controller
{
    /**
     * Returns a collection of Task
     *
     * @QueryParam(name="projectId", nullable=true, requirements="\d+")
     * @QueryParam(name="name", nullable=true, description="Project Name")
     * @QueryParam(name="assignee", nullable=true)
     * @QueryParam(name="depth", nullable=true)
     *         *
     * @param ParamFetcher $paramFetcher
     * @ApiDoc()
     *
     * @return JsonResponse
     */
    public function cgetTaskAction(ParamFetcher $paramFetcher)
    {
        foreach ($paramFetcher->all() as $criterionName => $criterionValue) {
            // some logic here, eg building query
        }

        $results = // query database using criteria from above

        // this is just a simple example how to return data
        return new JsonResponse($results);
    }
}
