I have been using SolrJ, the Java client for Apache Solr server, at my work. But it is disheartening to see that there are hardly any resources available online for it. Even the wiki on the parent site is kind of a "noob" guide !

There are few blogs like these which would get you started with SolrJ but no advanced stuff.

I would love to see if there are folks who have worked with SolrJ and could help me out by giving some pointers to valuable resources around it.
