Create index with mapping

To define or add a mapping, we have to use the Mapping API. Mapping for a type, like anything else, is represented in JSON.

Mapping APIs will let you do the following:

• Create a new index with mappings
• Add a new type to an existing index
• Add a new field to an existing type

First, let's create an index named chapter3 and define the mapping for the user type. The mapping for theuser type is defined as a JSON document as shown next.

Note that the HTTP method used for the request is PUT.

#Delete existing index if anyDELETE chapter3PUT chapter3 {   "mappings": {     "user": {       "properties": {         "age": {           "type": "integer"         },         "email": {           "type": "keyword"         },         "gender": {           "type": "keyword"         },         "id": {           "type": "integer"         }, "last_modified_date": ...
