$qb = $em->createQueryBuilder();
$qb->select('c')
  ->from('myBundle:Client', 'c')
  ->where('c.name LIKE :data')
  ->orderBy('c.name', 'ASC')
  ->setParameter('data', '%'.$data.'%');
   $query = $qb->getQuery();  
   $entities = $query->getResult();

Answer 1

you have to use methods like join, innerJoin or leftJoin

see http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/query-builder.html
