I am not surprised - my head started to hurt when I thought about it!

In fact, this approach is not the best in my opinion...one probably needs to materialize data in some other more facets-friedly system (e.g. solr, elastic search) to gain good performances (I might be wrong but this is what my - limited - experience told me).
Woah there!
I would say that is exactly where a faceted browser stops.
If there is free text search going on, then it isn’t really doing Linked Data, or it is doing much more in addition.
(This is the Linked Data list.)
So I would say that some constraints are that a faceted browser is something that lets you look at things identified by Linked Data URIs. It shows facets of those URIs, primarily by the Linked Data look up (through SPARQL or URI resolution), and in particular, doesn’t do (a lot of?) facets from text search engines especially if they don’t represent their data as RDF.
