Open index
Introduced 1.0
The open index API operation opens a closed index, letting you add or search for data within the index.
Example
POST /sample-index/_open
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 indices. |
| allow_no_indices | Boolean | Whether to ignore wildcards that don’t match any indices. Default is true. |
| expand_wildcards | String | Expands wildcard expressions to different indices. Combine multiple values with commas. Available values are all (match all indices), open (match open indices), closed (match closed indices), hidden (match hidden indices), and none (do not accept wildcard expressions). Default is open. |
| ignore_unavailable | Boolean | If true, OpenSearch does not search for missing or closed indices. 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. |
| master_timeout | Time | How long to wait for a connection to the master node. Default is 30s. |
| timeout | Time | How long to wait for a response from the cluster. Default is 30s. |
