I installed Faceted Search and enabled the content type facet and got a bunch of blocks that I have questions about. I expected to just see one block for the search by content type facet but I got several:
press_release_search - Related categories
press_release_search - Keyword search
press_release_search - Guided search
press_release_search - Current search
press_release_search - Sort options

The Keyword search block is the only one that shows up when I enable it so what are the other ones on this list hear for? What are they doing? How do I make them work?

Thanks!
