Hi all, is it possible to retrieve all indexes by their alias? I need the inverted way like described in RestGetIndicesAliasesAction.class (Line 59). Such give me all indices pointed to given alias.

To be more concrete: I'll be able to rebuild an index "my\_index\_v1" to "my\_index\_v2", pointed to the alias "my\_index". The process itself is well known by myself. My problem is to calculate the next number for \_v.. in a generic way. So my idea was to get the index name, which is pointed to the known alias, parse them, get the \_v sufix and create a new index based on the result of parsing, adding them to the alias,...... , remove the old index from alias.

Hey Alex, Currently, your only option is to get all the aliases and filter to the one you want. Does sound like a good idea. Please feel free to open an issue on github.

Thanks Boaz, the problem is not the filtering, more the retrieving of alias "containg indices"-data" 😉 Am Montag, 4.

Hi Alex, Not sure I follow. If you do curl -XGET "[http://localhost:9200/\_aliases/](http://localhost:9200/_aliases/)" , you get { "index1": { "aliases": { "alias1": {} } }, "index2": { "aliases": { "alias2": {}, "alias1": {} } } } Where you have all the information you need?

Ok that's an idea. But i'm using th java api. can you post the java api call. Cheers, Alex Am Montag, 4.

Well, the example is in the same RestGetIndicesAliasesAction you referred to. You do a cluster state request: client.admin().cluster().prepareState().setFilterNodes(true).setFilterRoutingTable(true).get() The in the response: MetaData metaData = response.getState().metaData(); for (IndexMetaData indexMetaData : metaData) .... You'd have to look at indexMetaData.aliases().containsKey("alias") Cheers, Boaz On Mon, Nov 4, 2013 at 2:48 PM, Alexander Kley [alexander.kley@gmail.com](mailto:alexander.kley@gmail.com)wrote: > Ok that's an idea.
