Make a RangeFilter that visits only docs in your time period, then run a search w/ a custom HitCollector that looks at the source of each doc and tallies up the results? For performance, you'll probably need to load the source using FieldCache (FieldCache.DEFAULT.getStrings(...)).
Or, use Solr's faceted search, or http://www.browseengine.com, or some other facets impl, to tally up the sources.
