Unable to extend Search class

[jariesdev]

I'm trying to extend the Search but getting an error:

use ONGR\ElasticsearchDSL\Search;

class ProductSearch extends Search
{
}

Error on private initializeSerializer method:

`Cannot access property ElasticSearch\Searches\ProductSearch::$serializer`

PHP: 7.2.26

Hey, Is there a reason you want to extend it?
