URL parameters

All get settings parameters are optional.

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.
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 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`.
