Hello, i am trying to use word\_delimiter for existing indexes, because all the hyphens are ignored while search for example "test-test" is searched as two separate patterns "test test" instead of test-test.

Documentations is not useful at all, there's nothing which help me out.

I've tried a lot of thinks from documentation but they just not work, and there's no clear docs and examples.

[https://bpa.st/D6IQ](https://bpa.st/D6IQ) there's what i am trying.

And the result.

```auto
{"error":{"root_cause":[{"type":"security_exception","reason":"action [indices:admin/create] is unauthorized for user [elastic]"}],"type":"security_exception","reason":"action [indices:admin/create] is unauthorized for user [elastic]","caused_by":{"type":"illegal_state_exception","reason":"There are no external requests known to support wildcards that don't support replacing their indices"}},"status":403}
```
