My data is 492,000 records of book data. I am faceting on 4

Format and language are fairly simple as their are only a few
unique terms. Author and subject however are much different in
that there are thousands of unique terms.
When encountering difficult issues, I like to think in terms of the
user interface. Surely you're not presenting 400k+ authors to the
users in one shot. In Collex, we have put an AJAX drop-down that
shows the author facet (we call it name on the UI, with various roles
like author, painter, etc). You can see this in action here:

type in "da" into the name for example. I developed a custom request
handler in Solr for returning these types of suggest interfaces
complete with facet counts. My code is very specific to our fields,
so its not usable in a general sense, but maybe this gives you some
ideas on where to go with these large sets of facet values.
