Basic example

  meilisearch do
    attribute :id, :title, :alt_titles, :content_rating, :content_type, :description
    
    embedders do
        text: {
            source: "huggingFace",
            model: "BAAI/bge-base-en-v1.5",
            documentTemplate: description,
        }
    end
  end
