These slide belonged to the presentation I hold to my colleagues in Göttingen as an introduction to Apache Solr open source search engine. In the structure I followed Trey Grainger and Timothy Potter excellent Solr in Action book (Manning, 2014), and I took some of the examples form there. Some others come from the examples bundeled with Solr, and from the projects I had opportunity to work with in the past (eXtensible Catalog and Europeana). These slides don't go too deep, if you want to know more about the topic, just drop me an email, or consult with the references on the last slide. Happy searching!
