The update operation doesn't work

[ivannis]

For example, for the given document

<?php
namespace Acme\AcmeDemoBundle\Document;

use ONGR\ElasticsearchBundle\Annotation as ES;
use ONGR\ElasticsearchBundle\Document\DocumentInterface;
use ONGR\ElasticsearchBundle\Document\DocumentTrait;

/**
 * @ES\Document
 */
class Content implements DocumentInterface
{
    use DocumentTrait;

    /**
     * @var string
     *
     * @ES\Property(name="name", type="string")
     */
    private $name;

    /**
     * {@inheritdoc}
     */
    public function getName()
    {
        return $this->name;
    }

    /**
     * {@inheritdoc}
     */
    public function setName($name)
    {
        $this->name = $name;

        return $this;
    }
}

If you create one

$manager = $this->get("es.manager");

$content = new \Acme\AcmeDemoBundle\Document\Content();
$content->setId("myCustomId");
$content->setName("Acme");

$manager->persist($content); 
$manager->commit();

When you try to update an existing document you never can update it

$manager = $this->get("es.manager");
$repository = $manager->getRepository('AcmeDemoBundle:Content');
$document = $repository->find('myCustomId');

$content->setName("Another Name");
$manager->persist($document); // The persist method never send an "update" bulk operation to elasticsearch
$manager->commit();

And look in the index

curl -XGET localhost:9200/my_index/my_type/_search?pretty

The content never change. I think that the problem is in the persist method of the Manager class https://github.com/ongr-io/ElasticsearchBundle/blob/master/ORM/Manager.php#L103-L107 that always sends the "create" operation. The Connection class never send any update option upsert, doc_as_upsert ... in the bulk method https://github.com/ongr-io/ElasticsearchBundle/blob/master/Client/Connection.php#L93-L115
