Your application isn't aware of Cassandra only Solr. The idea of Solandra is to use Cassandra as a backend for Solr. Solr has a distributed search mechanism already so by making Solr Cassandra aware it can auto-shard and manage distributed queries for you, with replication and failover etc
As for examples the code comes with a demo app mentioned in the readme.
