'faceted search' versus 'views with exported filters'

I've seen Faceted search in action on a live D5 site, both from outside and inside, and that was impressive.

I'm currently developing a website on D6, and had a need for 'advanced search' which is different from standard one.
I've created a View with 7 exported filters (only 2 of them are taxonomies, 1 is date_published, and the rest are text fields for CCK search). It works as expected, and "on the surface" seems equivalent to 'Faceted search' in functionality.

Could someone please elaborate on the differences between the two solutions? I want to be sure I know what I'm missing with my Views-based search approach.
