How make Shopware.form.field.Search works with ManyToOne association in backend with ExtJs?

Hi guys! I just wanted to you to know that I fixed that i just had to add to my backend controller those lines:

   protected function getDetailQuery($id) {
        $builder = parent::getDetailQuery($id);

        $builder->leftJoin('shop_comments.shop','shop');
        $builder->addSelect(['shop']);

        return $builder;
    }

    protected function getListQuery() {
        $builder = parent::getListQuery();

        $builder->leftJoin('shop_comments.shop','shop');
        $builder->addSelect([('shop')]);

        return $builder;
    }

I just missed them in documentation ! :)
