He is also a speaker for various conferences around the world, such as Lucene Eurocon, Berlin Buzzwords, and ApacheCon.

Rafa? began his journey with Lucene in 2002, and it wasn't exactly love at first sight. When he came back to Lucene in late 2003, he revised his thoughts about the framework and saw the potential in search technologies. Then Solr came along and that was it. He started working with ElasticSearch in the middle of 2010. Currently, Lucene, Solr, ElasticSearch, and information retrieval are his main points of interest.

Rafa? is also the author of Apache Solr 3.1 Cookbook and the update to it—Apache Solr 4 Cookbook—published by Packt Publishing.
