So it means that distributed search is not a basic component in Solr project.
I think you just need load balancing. Solr is not a load balancer, you need to find something that works for you and configure that elsewhere. Solr works fine without persistent connections, so simple round robin DNS but it works find.
Depending on your usage/loads/requirements it may or may not make sense to have your master DB in the mix.
Stu is referring to Federated Search - where each index has some of the data and results are combined before they are returned. This is not yet supported out of the "box"
