`_id` field

Each document indexed is associated with a _type (see the section called “Mapping Types edit”) and an_id. The _id field is not indexed as its value can be derived automatically from the _uid field.

The value of the _id field is accessible in certain queries (term, terms, match, query_string,simple_query_string), but not in aggregations, scripts or when sorting, where the _uid field should be used instead:

# Example documents

PUT my_index/my_type/1

{

  "text": "Document with ID 1"

}

PUT my_index/my_type/2&refresh=true

{

  "text": "Document with ID 2"

}

GET my_index/_search

{

  "query": {

    "terms": {

      "_id": [ "1", "2" ] 

    }

  }

}

COPY AS CURL VIEW IN CONSOLE

Querying on the _id field (also see the ids query)
