So if we don't add fields parameter to the request query, Elasticsearch will automatically attempt to determine the existing fields in the index's mapping that are queryable, and perform the search on those fields. The different types of queries have been described below. As soon as the query assembles the complete list of items it executes the appropriate low-level query for every term, and finally combines their results to produce the relevance score of every document.
