I do not understand the idea as a default filter is a filter applied when the search results are displayed and thus can be given as URL parameters.

I do not understand the idea as a default filter is a filter applied when the search results are displayed and thus can be given as URL parameters.

The idea is that defaultSearchInput agg filters will be applied for every search using the resource search box (place above facets). At this time, a search in this box, will remove all existing filters and run a search only with "q=search_input_value" as query string
