I know there is a way to get all the aliases associated with given index, but is there a way to get all the indices for a given alias?
Input: Alias
Output: List[Index]
The only approach I know of is to get aliases and iterate through each one of them, but it can be expensive if we have too many indices/aliases in production. Please let me know. Thank you.
Would like to know ES API and Java/Scala API. I am using Elastic4s client, BTW.
Thank you!

Hi,
Use:
GET indexname/\_alias
Refer to the documentation here:
[https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-aliases.html#alias-retrieving](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-aliases.html#alias-retrieving)

@msimos I looked at the document and didn't find the answer (unless I overlooked something). Your answer gives me alias, given an index name. My request is opposite to your answer. Following is what I am expecting
Input: AliasName
Output: List of Indices associated with that Alias
Example:
Index: esIndex1, esIndex2
Alias: esIndexAlias
```
POST /_aliases
{
"actions" : [
{ "add" : { "index" : "esIndex1", "alias" : "esIndexAlias" } },
{ "add" : { "index" : "esIndex2", "alias" : "esIndexAlias" } }
]
}
```
Now, I want to get both the indices (esIndex1 and esIndex2) for a given alias (esIndexAlias)

Try:
GET /\_alias/esIndexAlias

@msimos cool, that should work. Any idea about associated Java API? If you know about elastic4s, its a bonus 🙂
