Faceted Searching is a must have feature for enhancing findability and user engagement in enterprise search UI. The Faceted Searching features of Apache Solr have been a major factor in it's popularity, but many Solr users don't fully appreciate all of the capabilities that are available. In this session we will deep dive into the different types of data facets that Solr supports, discussing in detail the various options that can be used to explore them. We will also review some specific techniques for dealing with several complex use cases, and discuss some performance "gotchas" and how to avoid them.
