Faceted Browsing-- How does it work?

I installed the "facet by metadata" plugin (http://omeka.org/add-ons/plugins/facet-by-metadata/) and the only place the "facets" show up is once you are already in a record. I'd like to be able to refine searches with facets. What should I do?

'Facets' might have been a misleading name, come to think of it. It really just does an advanced search, with values pre-filled from the record page. For what you are describing, that's basically just doing an advanced search.
