Reading a document (student data)

With REST client, enter the following:

• URL: http://localhost:9200/students/student/1
• Method: GET

With Kibana, enter the following:

GET students/student/1

You will get the following JSON as an output:

{    "_index": "students",    "_type": "student",    "_id": "1",    "_version": 1,    "found": true,    "_source": {        "name": "Nilang",        "standard": 1,        "division": "B",        "gender": "M"    }}

If you use any existing _id, Elasticsearch will simply update that record with current values. The _version attribute represents the number of times the records are updated. ...
