There's no real magic about the index structure, it's just the same as non-cloud Solr. So presumably you have example and example2 directories or some such. They're just standard Solr installations with the index in the usual place, the docs for the particular shard are stored in the data/index directories under example and example2.
SolCloud is simply doing the usual querying for you, it sends the request to _all_ shards and assembles the response. The only time hashing on the <uniqueKey> comes into play is when SolrCloud is deciding what shard to send the document to during indexing AFAIK. Likewise, going to specific Admin pages for each node will show you stats for that particular node. If you really want to, you can probably just fire up the Solr node without any of the ZK parameters and it'll be out of the cloud. But an easier way is just to go into the admin>>cloud page and click on the nodes displayed. Then click on the core (probably "collection1") and you'll see statistics for that particular node.
