 The video above shows us how to use Solr toperform collaborative filtering, categorical classification, and subsequent hirerarchical-based recommendations, and concept extraction/concept based recommendations.

Searching text is what Solr is known for, but did you know that many companies receive an equal or greater business impact through implementing a recommendation engine in addition to their text search capabilities? With a few tweaks, Solr (or Lucene) can also serve as a full featured recommendation engine. Machine learning libraries like Apache Mahout provide excellent behavior-based, off-line recommendation algorithms, but what if you want more control? This talk will demonstrate how to effectively utilize Solr to perform collaborative filtering (users who liked this also liked…), categorical classification and subsequent hierarchical-based recommendations, as well as related-concept extraction and concept based recommendations. Sound difficult? It’s not. Come learn step-by-step how to create a powerful real-time recommendation engine using Apache Solr and see some real-world examples of some of these strategies in action.

For a JRuby-only project you can also use the official mongodb-ruby-driver. It includes native Java components (instead of bson_ext) and performs splendidly! Also it seems like jmongo is dead.
