# cat aliases
|
|
Introduced 1.0
|
|
{: .label .label-purple }
|
|
|
|
The cat aliases operation lists the mapping of aliases to indices, plus routing and filtering information.
|
|
|
|
## Example
|
|
|
|
```json
|
|
GET _cat/aliases?v
|
|
```
|
|
|
|
To limit the information to a specific alias, add the alias name after your query:
|
|
|
|
```json
|
|
GET _cat/aliases/<alias>?v
|
|
```
|
|
|
|
If you want to get information for more than one alias, separate the alias names with commas:
|
|
|
|
```json
|
|
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]({{site.url}}{{site.baseurl}}/opensearch/rest-api/cat/index#common-url-parameters), you can specify the following parameters:
|
|
|
|
Parameter | Type | Description
|
|
:--- | :--- | :---
|
|
local | Boolean | Whether to return information from the local node only instead of from the master node. Default is false.
|
|
expand_wildcards | Enum | Expands wildcard expressions to concrete indices. Combine multiple values with commas. Supported values are `all`, `open`, `closed`, `hidden`, and `none`. Default is `open`.
|
|
|
|
## Response
|
|
|
|
The following response shows that `alias1` refers to a `movies` index and has a configured filter:
|
|
|
|
```json
|
|
alias | index | filter | routing.index | routing.search | is_write_index
|
|
alias1 | movies | * | - | - | -
|
|
.kibana | .kibana_1 | - | - | - | -
|
|
```
|
|
