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

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.
