Here is my Vega-lite code in Kibana. I already tried changing the property field and tried wrapping code in a spec tag, and declaring the row field inside encoding. I commented this parts in the code, as I am not sure what to do.

That information was helpful, and I've identified a few misunderstandings that will help you with defining Vega specs in the future.
1. Like I wrote in the Vega-Lite tutorial, you should be applying a `flatten` transform because Vega-Lite requires it: [https://www.elastic.co/guide/en/kibana/current/vega-lite-tutorial-create-your-first-visualizations.html](https://www.elastic.co/guide/en/kibana/current/vega-lite-tutorial-create-your-first-visualizations.html)
2. Your `facet` was using the wrong name. The JSON response contains `key`, not `iName.keyword`.
3. Your `encoding` contains the wrong level of keys. Once you transform the results, you need to encode the _inner_ level like `flattened_name.key` and `flattened_name.doc_count`
Putting this together, here is the spec that I made based on your request [https://gist.github.com/wylieconlon/e72b30da35615fc6c59b3a0eef779117](https://gist.github.com/wylieconlon/e72b30da35615fc6c59b3a0eef779117)

Thank you so much @wylie, it is working. But I can't manage to size my small multiples.
I was able to split by row and columns, but it is so big that the plots don't fit in a dashboard. Tried this below, but no success:
```
config: {
view: {
width: 100
height: 100
}
}
autosize: {
type: fit
}
```

View composition doesn't work well with autosizing, but you can set `height` and `width` inside your `spec` property next to your `mark`

@wylie thanks again for the help.
I'm unable to find how to declare spec property (although it was commented in my code, I didn't use). It returns me "Invalid specification".
I'm using vega-lite schema, is it possible? Or spec is just for vega schema?

In the JSON that I previously sent you, there is a property called `spec`. Inside that you can provide a `height` or `width`
