Elasticsearch is a distributed search and analytics engine that excels at handling large volumes of data in real time. When we have such a large repository of data, singling out the most suitable context can be a grueling task. And precisely that’s why we query. Querying allows us to search and retrieve relevant data from the Elasticsearch index with relative ease. Elasticsearch uses query DSL for this purpose. Query DSL is a powerful tool for executing such types of search queries.
