And here I am totally mistaken, of course SOLR gives you it out-of-the-box (you don't have to write 99 Lucene queries if your simple attribute has 99 different values); but for SQL, you will have to... it seems possible only in theory; you really need to be master in SQL to write fast-performing queries with 'GROUP BY' clauses, and analyze execution plan, etc... :((( SOLR gives it out-of-the-box. Thanks!
