Please format your code, logs or configuration files using `</>` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and not the citation button. It will make your post more readable.

Or use markdown style like:

````
```
CODE
```

````

This is the icon to use if you are not using markdown format:

There's a live preview panel for exactly this reasons.

Can you add a `terms` agg on `_index` field?
