Filter applied to specific data view (index pattern)

Hi,

I find it powerful to mix content from different types of indexes in Kibana dashboards, but have a difficult time setting up useful dashboards because of global filtering. I do however want to use filters and add controls for easy selection of content to view.

A recent example is that I want to compare a set of collected values in an index matched by data_view_a with reference lines based on values in an index matched by data_view_b. data_view_a and data_view_b don't have many filed in common, and as soon as a filed specific to one data view is included in the filter everything related to the other is filtered out.

What would help is the possibility to have filters targeting only a specific data view. For example a query on the form data_view_a.source : source_1 and data_view_b.reference_set : reference_set_2 or similar constructions for other types of filters.

The best solution I've found so far is to add missing fields to my data views, emitting a fixed value which will never occur in the real data from that field in other data views. Then I include that value among the ones to filter for. But if I want include more data views along with specific filters it quickly becomes cumbersome.

I'm quite new to Kibana, so maybe I'm doing things backwards and that there are better ways of solving this. Yet I find others having similar issues that indicate some feature may be missing.
One example is Apply filter for individual visualization in dashboard

Any ideas for how to better achieve what I want to do?

The advanced setting courier:ignoreFilterIfFieldNotInIndex could help with this.
