Hi all,

I want to test the reindex API follow the [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-reindex.html).

Did anybody try to reindex based on pattern index, like:

> ```
> POST /_reindex
> {
> "source": {
> "index": "test*"
> },
> "dest": {
> "index": "new_test*"
> }
> }
> 
> ```

I want to match all index that contain "test" in their name.

It is working like that ? Can I reindex several indices to seceral new indices ?

Thanks in advance,  
Alex

Reindex doesn't have any support for reversing a pattern into the destination index name. You can do with with a script. This PR:

> This can be a common case with beats in case the template changes between two ve…rsions and the old data should be reindex with the new templates.

Has documentation for how to do it in 5.0.0 with the `painless` sandboxed dynamic scripting language. You'd have to do it with groovy in 2.3 or 2.4.

The trouble with doing several indexes at once is that the process isn't incremental. They all finish at the same time.
