> The performance of a query with facets is relative to the number of documents that match
the user query - so queries that match lots of documents (e.g. *) perform pretty terrible
in an environment with lots of data.  This is even if the query and all facets are independently
very fast.
> To reproduce, create a large index with some term that's in most documents, then query
on that term with lots (~200) trivial term-based facets.
