Filtres multiples sur symfony 3.4

Bonjour,

Voila je rencontre un petit problème avec mon code.

J'essaie de filtrer mes utilisateurs par date début et date fin, mode de paiement zone de livraison(nom=stocke le nom de la zone de livraison) et nb Commandes, j'ai créé un form Type, une action une fonction dans le repository

class FilterClientsType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('dateDebut', DateType::class, array(
                'label'=>false,
                'widget' => 'single_text',
                'html5' => true,

            ))
            ->add('dateFin', DateType::class, array(
                'label'=>false,
                'widget' => 'single_text',
                'html5' => true,

            ))

            ->add('Filter', SubmitType::class, array(
                'attr' => array(
                    'class' => 'btn btn-primary',
                )
            ));
    }/**
 * {@inheritdoc}
 */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => null
        ));
    }

}

class UtilisateurController extends Controller
{

    public function listAction(Request $request)
    {
        $form = $this->createForm(FilterType::class);
        $form->handleRequest($request);
        if ($form->isSubmitted() && $form->isValid()) {
            $dateDebut = $form->get('dateDebut')->getData();
            $dateFin = $form->get('dateFin')->getData();

            ->addSelect('COUNT(cmd.id) as nbCommandes');

        if (!is_null($dateDebut) && !is_null($dateFin) && $dateFin >= $dateDebut && !is_null($modePaiement) && !is_null($nom) && !is_null($nbCommandes)) {
            $qb->where('cmd.dateCommande BETWEEN :dateDebut AND :dateFin')

Je cherche à faire fonctionner ma requête car pour l'instant c'est ça qui bloque le problème est dans le nbCommandes qui n'existent pas dans la bdd donc je dois le calculer avec le compte de nombre de commandes de chaque utilisateur
Merci pour l'aide
