    Thanks for the announcement.

    The Solr Reference Guide ( is lately behind the releases.

    New features such as SynonymGraphFilterFactory is still undocumented, any other sources beside the ref guide you can recommend?

    I would say that JIRA related to features introduced in new Lucene and Solr version bring lots of knowledge related to those features. In some cases you can even find performance tests and discussions, lots of examples and so on.
