That's really the whole point though - rather than slamming your whole cluster with every search, the majority of people are just searching today - which will have only a fraction of the data and will be able to hold up very well to a large load. This is also how you can do really fast NRT on a huge data set - it only has to happen on todays shard. News sites have been using the trick forever with Lucene. - Mark
