In my presentation, I will introduce you to Gally, an advanced searchandising engine built on top of Symfony, API Platform, and Elasticsearch. During the talk, I will guide you through the process of setting up and configuring Gally alongside the Gally bundle for Sylius. You will learn what features Gally offers, how the Sylius integration works, and how to extend Gally to deal with custom entities for your specific use case.
