Sorry for not knowing a lot since I am very new...
I have been playing around with using the sub aggregations in Kibana's visualization tab. One aspect of it I don't understand is the filter metric. You can specify a new sub bucket to be of type filter and then it creates a new text field below it called "filter 1." I have figured out that you can type words in it and then Kibana will filter the elastic search data with those words. However, what I am curious about is how to limit the scope of the filter. Can I make it only look at certain fields? Can I pass it filters like I can on the console? Is there a better way to filter data based off one field that shares values with other fields in the same "data point"?
I have been reading a lot about how to use filters from the console, I'm just curious how to use that textfield in the visualization editor.

The filters in the filter aggregation support the [Elasticsearch query string syntax](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#query-string-syntax) which does support limiting terms to a specific field and a whole lot more
```auto
fielda:foo fieldb:"bar baz"
```

but is that the same in the filter bar I described? The one in kibana? Because if I pass a query like it describes in the link it doesn't work.
