Delete document

Introduced 1.0 {: .label .label-purple }

If you no longer need a document in your index, you can use the delete document API operation to delete it.

Example

DELETE /sample-index1/_doc/1

Path and HTTP methods

DELETE /<index>/_doc/<_id>

URL parameters

Parameter	Type	Description	Required
<index>	String	The index to delete from.	Yes
<_id>	String	The ID of the document to delete.	Yes
if_seq_no	Integer	Only perform the delete operation if the document's version number matches the specified number.	No
if_primary_term	Integer	Only perform the delete operation if the document has the specified primary term.	No
refresh	Enum	If true, OpenSearch refreshes shards to make the delete 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.	No
routing	String	Value used to route the operation to a specific shard.	No
timeout	Time	How long to wait for a response from the cluster. Default is 1m.	No
version	Integer	The version of the document to delete, which must match the last updated version of the document.	No
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 delete version 3 of a document, use /_doc/1?version=3&version_type=external.	No
wait_for_active_shards	String	The number of active shards that must be available before OpenSearch processes the delete request. Default is 1 (only the primary shard). Set to all or a positive integer. Values greater than 1 require replicas. For example, if you specify a value of 3, the index must have two replicas distributed across two additional nodes for the operation to succeed.	No
