Symfony + Redis - how to search by tag

Question

As of version 3.x Symfny supports Redis as a cache.

It is working fine, but only if I want to get some data from cache like:

$redis = $this->get('cache.app');

$cached = $redis->getItem('video#32');
$data = $cached->get();

if (!$cached->isHit()) {
    $cached->set([
        'users' => [
            $userId => [
                'username' => $userName,
                'refresh' => new \DateTime()
            ]
        ]
    ])->tag('stack, overflow, symfony, support');
    $redis->save($cached);
}

Is it possible to search/find all rows from cache with tag stack and support? I was searching for it in the symfony docs but there is no information about it. If it is not possible, when and how I should use tags if I cannot use them for searching?

btw: there is information that we need to use TaggedCacheItemInterface but several days later it was dropped here
