# Get settings
Introduced 1.0
{: .label .label-purple }

The get settings API operation returns all the settings in your index.

## Example

```json
GET /sample-index1/_settings
```
{% include copy-curl.html %}

## Path and HTTP methods

```
GET /_settings
GET /<target-index>/_settings
GET /<target-index>/_settings/<setting>
```

## URL parameters

All update settings parameters are optional.

Parameter | Data type | Description
:--- | :--- | :---
&lt;target-index&gt; | 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.
&lt;setting&gt; | String | Filter to return specific settings.
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 | String | 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 master node. Default is false.
master_timeout | Time | How long to wait for a connection to the master node. Default is `30s`.
