Target non-existing entity in querybuilder (ManyToMany relationship)

Question

I can't seem to target the JoinTable 'product_features' in a query builder:

     /**
     * @ORM\ManyToMany(targetEntity="AttributeOption", cascade={"persist"})
     * @ORM\JoinTable(name="product_features",
     *      joinColumns={@ORM\JoinColumn(name="product_id", referencedColumnName="id")},
     *      inverseJoinColumns={@ORM\JoinColumn(name="attribute_option_id", referencedColumnName="id")}
     *      )
     */
    protected $features;

I did discover that you can join a non-related table but you need to call it by the entity in order to do so. Am I right? There is no entity since it's just a table generated by the ManyToMany mapping.

This is what I've tried but it does target the targetEntity 'AttributeOption':

$query
      ->innerJoin('p.features', 'f')
      ->setParameter('filters', $filters)
      ->andWhere('f.id IN (:filters)');

I really need the product_features table in my query. Please, help me out!

Thanks in advance!
