CAT aliases
Introduced 1.0
The CAT aliases operation lists the mapping of aliases to indexes, plus routing and filtering information.
Example
GET _cat/aliases?v
To limit the information to a specific alias, add the alias name after your query:
GET _cat/aliases/<alias>?v
If you want to get information for more than one alias, separate the alias names with commas:
GET _cat/aliases/alias1,alias2,alias3
Path and HTTP methods
GET _cat/aliases/<alias>
GET _cat/aliases
URL parameters
All CAT aliases URL parameters are optional.
In addition to the common URL parameters, you can specify the following parameters:
Parameter | Type | Description |

expand_wildcards | Enum | Expands wildcard expressions to concrete indexes. Combine multiple values with commas. Supported values are all , open , closed , hidden , and none . Default is open . |
