Open up your user base to the data! Almost everybody knows how to search. This talk describes through an interactive demo based on open source Hue how users can graphically search their data in Hadoop with Apache Solr. The session will detail how to get started with data indexing in just a few clicks and then explore several data analysis scenarios. The open source Hue search dashboard builder, with its draggable charts and dynamic interface lets any non-technical user look for documents or patterns. Attendees of this talk will learn how to get started with interactive search visualization in their Hadoop cluster.
