Open index

Introduced 1.0

The open index API operation opens a closed index, letting you add or search for data within the index.

Path and HTTP methods

POST /<index>/_open

Parameter	Type	Description
<index>	String	The index to open. Can be a comma-separated list of multiple index names. Use `_all` or * to open all indexes.

All parameters are optional.

Parameter	Type	Description
allow_no_indices	Boolean	Whether to ignore wildcards that don’t match any indexes. Default is `true`.
expand_wildcards	String	Expands wildcard expressions to different indexes. Combine multiple values with commas. Available values are all (match all indexes), open (match open indexes), closed (match closed indexes), hidden (match hidden indexes), and none (do not accept wildcard expressions). Default is `open`.
ignore_unavailable	Boolean	If true, OpenSearch does not search for missing or closed indexes. Default is `false`.
wait_for_active_shards	String	Specifies the number of active shards that must be available before OpenSearch processes the 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 request to succeed.
cluster_manager_timeout	Time	How long to wait for a connection to the cluster manager node. Default is `30s`.
timeout	Time	How long to wait for a response from the cluster. Default is `30s`.
wait_for_completion	Boolean	When set to `false`, the request returns immediately instead of after the operation is finished. To monitor the operation status, use the Tasks API with the task ID returned by the request. Default is `true`.
task_execution_timeout	Time	The explicit task execution timeout. Only useful when wait_for_completion is set to `false`. Default is `1h`.
