Search results: Allow users to exclude a specific filter value

[kjacks]

"Would it be possible to be able to have a widget that excludes datasets in a search as well as a widget that we already have that includes datasets. ....or a button to 'select all' so we can then uncheck datasets. We have some datasets that kind of pollute our search results but we still want them on our instance."

@sunu out of curiousity - does elasticsearch support this kind of exclude filter out of the box? Or would this require a lot of additional configuration?

We can probably use must_not query for that.
