Data modeling for restaurants

Firstly, we need to see the aspects of data and model it around a JSON document for Elasticsearch to make sense of the data. A restaurant has a name, its location information, and rating. To store the location information, Elasticsearch has a provision to understand the latitude and longitude information and has features to conduct searches based on it.
