Deleting a document is fairly straightforward. This example shows how to delete our previous customer with the ID of 2:
_delete_by_query API to delete all documents matching a specific query.
It is worth noting that it is much more efficient to delete a whole index
instead of deleting all documents with the Delete By Query API.
