I need to keep things in taxonomies so that I can retain the faceting behaviour in search, but I would also like to set up a more conventional way of drilling down through pages (and I'm hoping Views will let me do this). I'm wondering if I can have a Views page that lists all the items in one taxonomy package, but when a user clicks on one of those items, they are taken to another set of taxonomies. When they select something from that page, they are given only the list of nodes that have both taxonomies applied to them.
It will probably be too confusing to explain exactly what I'm working with, so let's say I was creating a page that collects government documents. Every node corresponds to one document, but every document will have a taxonomy for region (i.e., California, Texas, etc.) and department (i.e., Transportation, Education, etc.). So the first View would show all the states, and when they click on a state, they're taken to a list of departments. When they click on a department, they're shown a View that lists all the documents for that state.
I realize this is just faceting behaviour, but I've been requested to build something like this anyway.
