That's a fantastic answer, Shawn. To more directly answer Bernd's question: Bernard, shard your data once you've done reasonable performance optimizations to your single core index setup (see Chapter 9 of my book) and the query response time isn't meeting your requirements in spite of this. Solr scales pretty darned well horizontally -- so as you shard your data more and more, the query responses will get faster. At some extreme point there will be diminishing returns and a performance decrease, but I wouldn't worry about that at all until you've got many terabytes -- I don't know how many but don't worry about it.
