Update document
Introduced 1.0
If you need to update a document’s fields in your index, you can use the update document API operation. You can do so by specifying the new data you want in your index or by including a script in your request body, which OpenSearch runs to update the document.
Example
POST /sample-index1/_update/1
{
"doc": {
"first_name" : "Bruce",
"last_name" : "Wayne"
}
}
Script example
POST /test-index1/_update/1
{
"script" : {
"source": "ctx._source.secret_identity = \"Batman\""
}
}
Path and HTTP methods
POST /<index>/_update/<_id>
URL parameters
Parameter | Type | Description | Required |
---|---|---|---|
<index> | String | Name of the index. | Yes |
<_id> | String | The ID of the document to update. | Yes |
if_seq_no | Integer | Only perform the update operation if the document has the specified sequence number. | No |
if_primary_term | Integer | Perform the update operation if the document has the specified primary term. | No |
lang | String | Language of the script. Default is painless . | No |
require_alias | Boolean | Specifies whether the destination must be an index alias. Default is false. | No |
refresh | Enum | If true, OpenSearch refreshes shards to make the operation visible to searching. Valid options are true , false , and wait_for , which tells OpenSearch to wait for a refresh before executing the operation. Default is false . | No |
retry_on_conflict | Integer | The amount of times OpenSearch should retry the operation if there’s a document conflict. Default is 0. | No |
routing | String | Value to route the update operation to a specific shard. | No |
_source | Boolean or List | Whether or not to include the _source field in the response body. Default is false . This parameter also supports a comma-separated list of source fields for including multiple source fields in the query response. | No |
_source_excludes | List | A comma-separated list of source fields to exclude in the query response. | No |
_source_includes | List | A comma-separated list of source fields to include in the query response. | No |
timeout | Time | How long to wait for a response from the cluster. | No |
wait_for_active_shards | String | The number of active shards that must be available before OpenSearch processes the update 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 |
Request body
Your request body must contain the information you want to update your document with. If you just want to replace certain fields in your document, your request body must include a doc
object, which has the fields you want to update.
{
"doc": {
"first_name": "Thomas",
"last_name": "Wayne"
}
}
You can also use a script to tell OpenSearch how to update your document.
{
"script" : {
"source": "ctx._source.oldValue += params.newValue",
"lang": "painless",
"params" : {
"newValue" : 10
}
}
}
Upsert
Upsert is an operation that conditionally either updates an existing document or inserts a new one based on information in the object. In the sample below, the upsert
object updates the last name and adds the age
field if a document already exists. If a document does not exist, a new one is indexed using content in the upsert
object.
{
"doc": {
"first_name": "Martha",
"last_name": "Rivera"
},
"upsert": {
"last_name": "Oliveira",
"age": "31"
}
}
You can also add doc_as_upsert
to the request and set it to true
to use the information in doc
for performing the upsert operation.
{
"doc": {
"first_name": "Martha",
"last_name": "Oliveira",
"age": "31"
},
"doc_as_upsert": true
}
