Yes. &facet=false means "don't do any faceting". This is why you don't
get any facet data back. This is probably a bug in the solr-ruby code.
Version number 0.0.x is probably a hint about its production-ready
status :)
A distributed search system is easier to administer if you add a new
core that is the "distributor". It has no Solr data, but the
solrconfig.xml includes search requestHandlers that always search a
set of other cores. This is done with an "<invariants>" element that
hard-codes "cores" as your list.
