First cut of the version 8. Filters applied via url should return right selections of nodes, i.e
mysite.com/listings/dell/monitor/
where dell and monitor are taxonomy terms
just make sure you set number of nodes per page
/admin/config/taxonomy_facets/adminsettings
There are two source plugins. One that is usable with all entities in core, except for terms. The second source plugin for terms extends the first and add some extra data for the sake of exporting term hierarchy.
