So, what I call "faceted browsing" is the possibility to assist the user to "drill down" any result set. Something recent versions of SolR, Drupal, Blacklight, VuFind are proposing. Something which exists in DIALOG since decades (RANK command).
"overriding" instead of "replacing" is a reality in some parts of DSpace and is a long way in others. I know Mark Diggory keeps the target locked on this topic. Have a nice day!
