Get settings
Introduced 1.0
The get settings API operation returns all the settings in your index.
Path and HTTP methods
GET /_settings
GET /<target-index>/_settings
GET /<target-index>/_settings/<setting>
Path parameters
| Parameter | Data type | Description |
|---|---|---|
| <target-index> | String | The index to get settings from. Can be a comma-separated list to get settings from multiple indexes, or use _all to return settings from all indexes within the cluster. |
| <setting> | String | Filter to return specific settings. |
Query parameters
All get settings parameters are optional.
| Parameter | Data 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), which must be used with open, closed, or both. Default is open. |
| flat_settings | Boolean | Whether to return settings in the flat form, which can improve readability, especially for heavily nested settings. For example, the flat form of “index”: { “creation_date”: “123456789” } is “index.creation_date”: “123456789”. |
| include_defaults | Boolean | Whether to include default settings, including settings used within OpenSearch plugins, in the response. Default is false. |
| ignore_unavailable | Boolean | If true, OpenSearch does not include missing or closed indexes in the response. |
| local | Boolean | Whether to return information from the local node only instead of the cluster manager node. Default is false. |
| cluster_manager_timeout | Time | How long to wait for a connection to the cluster manager node. Default is 30s. |
