Get document

Get document

Introduced 1.0

After adding a JSON document to your index, you can use the get document API operation to retrieve the document’s information and data.

Example

GET sample-index1/_doc/1

copy

Path and HTTP methods

GET <index>/_doc/<_id>
HEAD <index>/_doc/<_id>

GET <index>/_source/<_id>
HEAD <index>/_source/<_id>

URL parameters

All get document URL parameters are optional.

Parameter	Type	Description
preference	String	Specifies a preference of which shard to retrieve results from. Available options are `_local`, which tells the operation to retrieve results from a locally allocated shard replica, and a custom string value assigned to a specific shard replica. By default, OpenSearch executes get document operations on random shards.
realtime	Boolean	Specifies whether the operation should run in realtime. If false, the operation waits for the index to refresh to analyze the source to retrieve data, which makes the operation near-realtime. Default is true.
refresh	Boolean	If true, OpenSearch refreshes shards to make the get operation available to search results. Valid options are `true`, `false`, and `wait_for`, which tells OpenSearch to wait for a refresh before executing the operation. Default is `false`.
routing	String	A value used to route the operation to a specific shard.
stored_fields	Boolean	Whether the get operation should retrieve fields stored in the index. Default is false.
_source	String	Whether to include the `_source` field in the response body. Default is true.
_source_excludes	String	A comma-separated list of source fields to exclude in the query response.
_source_includes	String	A comma-separated list of source fields to include in the query response.
version	Integer	The version of the document to return, which must match the current version of the document.
version_type	Enum	Retrieves a specifically typed document. Available options are `external` (retrieve the document if the specified version number is greater than the document’s current version) and `external_gte` (retrieve the document if the specified version number is greater than or equal to the document’s current version). For example, to retrieve version 3 of a document, use `/_doc/1?version=3&version_type=external`.
