The application also relates to a data output method, a data output device and electronic equipment.

Background

With the development of the e-commerce technology, the user can search related to the food and drink information through the life service App, and the search becomes one of more widely applied convenient life scenes.

However, the service information related to the dish is of a wide variety, and may be, for example, merchant information including the dish, takeout merchant information providing takeout subscription service for the dish, and efficacy information or cooking information of the dish. Under the condition that the user search requirement cannot be obtained, any single-category information is provided for the user, and the search requirement of the user cannot be met. For example, for a single dish, a plurality of ways of eating, such as a meal for entering a store, a meal for taking out, or a meal for cooking, may be included, and if the user's eating needs cannot be known, a search is performed based on dish information to obtain single category information that is not information that the user wants, for example, the user inputs "pickled Chinese cabbage", and the search result is merchant information including the word "pickled Chinese cabbage", such as "x pickled Chinese cabbage fish" or "x pickled Chinese cabbage fish rice", but the user has an original intention to know recipe information of pickled Chinese cabbage or take-out information related to pickled Chinese cabbage. In this case, the user needs to enter a website supporting the restaurant delivery service for retrieval or enter a recipe website for recipe query, so that the user retrieval process becomes complicated.
