So in solrconfig.xml update the queries in newSearcher and/or(?)
firstSearcher to include all the settings for a facet query with the desired
facets?  Does the cache get populated if the query string is *:* (I don't
want to risk a setup that doesn't hit any results and fails to populate the
cache..).  If the warming query might now take 25 seconds (maybe more for
more documents), I guess we might need to decrease the autocommit rate to
cut down on chance of overlapping warmers?
