How to setup Solr Replication with two search servers?

Question

Hi I'm developing rails project with sunspot solr and configure Solr replication. My environment: rails 3.2.1, ruby 2.1.2, sunspot 2.1.0, Solr 4.1.6.

Why replication: I need more stable system - oftentimes search server goes on maintenance and web application stop working on production. So, I think about how to make 2 identical search servers instead of one, to make system more stable: if one server will be down, other will continue working.

I cannot find any good turtorial with simple, easy to understand and described in details turtorial... I'm trying to set up replication on two servers, but I do not fully understand how replication working inside:

• synchronize data between two servers (is it automatic action?)
• balances search requests between two servers
• when one server suddenly stop working other should become a master (is it automatic action?)
• is there replication features other than listed?
