Can I obtain counts for terms and multi-word phrases within a set of
documents? E.g. can I use Solr to retrieve the number of times the phrase "Wall Street Journal" was mentioned in documents where fieldA = 'abc' and
fieldB = 'xyz' etc..?


I believe so. Isn't that just the number of docs returned for that query? You can pass arbitrary queries to Solr to facet on, too. I'd have a look at http://wiki.apache.org/solr/SimpleFacetParameters

See Solr's faceting capabilities.  http://lucene.apache.org/solr and
the wiki from there.  Faceting is built right in.
