Retrieve – GET:

# curl -XGET http://localhost:9200/Index_Name?pretty

# curl -XPOST http://localhost:9200/Index_Name/type/_update -d'
  {
      "doc": {
          "foo" : "bar"
      }
  }'

Delete:

# curl -XDELETE  http://localhost:9200/Index_Name

Index – Logical namespace which points to one or more shards in an ElasticSearch cluster and serves as the place to store related data.

Type – Within an index, you can define one or more types. A type is a logical category/partition of your index.

Document – Within a Type, a Document is a basic unit of information that can be indexed. For example, you can have a document for a single customer, another document for a single product, and yet another for a single order. This document is expressed in JSON format.
