// Recommendation templates: the agent reads out or describe the top result from the search,
// optionally proposing an action to do on it

// A recommendation from the system is followed by:
// - yes (= "positive_recommendation_reply_pair")
// - some form of search refinement (= "negative_recommendation_reply_pair")
// - a question (= "recommendation_search_question_pair")
// - closing the dialogue (= "recommendation_cancel_pair")
