Revision ee538a38-6895-46eb-8dab-11a45d28206c

Everything is in the question i need to load a custom product collection in frontend using smile elasticsuite. But i can't figure out how to do it. Do you guys have a working example ? 

` "smile/elasticsuite": "~2.10.13"`

So far this is the error i'm getting (which makes sense as the method is declared in smile and not in magento...but i don't understand why it's using the magento class instead of smile.

Thats the error I'm getting : 

> rror: Call to undefined method Magento\Catalog\Model\ResourceModel\Product\Collection\Interceptor::addSortFilterParameters() in /var/www/magento/vendor/smile/elasticsuite/src/module-elasticsuite-catalog/Plugin/LayerPlugin.php:87
