First, terminology clarification. fq is *filter* query. facet.query
is facet query.

facet Query has better performance that simple query (q).
The performance is (about?) the same, caches excluded. But fq's get
added to the filterCache, q's to the queryCache.
Here is the example.
http://localhost:8080/test_solr/select?q=*:*&facet=true&fq=state:CA&facet.mincount=1&facet.field=city&facet.field=sector&facet.limit=-1&sort=score+desc
--> facet by sector and city for state of CA.
Any idea how to optimize this query to avoid "q=*:*"?
In this case you could use q=state:CA and remove fq=state:CA, but
performance-wise as well as all other things considered, I'd stick
with what you've got - just warm those filterCaches up and your
performance should be quite acceptable. Report back with more details
if not.
