Path and HTTP methods

POST /<index-name>/_open

URL parameters

All parameters are optional.

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