Solr
• Search server, powered by Lucene
• Indexing/searching via HTTP, responses in XML, Ruby, PHP, Python, XSLT, etc
• Faceting
• Scalability: caching, replication, distributed search
• Integrates: spell checking, highlighting, more-like-this, clustering, rich document indexing, data import handling (RDBMS, and more)

Facets
• Sets, buckets
• (Un)common / similar metadata
• Useful for making sense of large datasets: navigation, foraging, context, visualization
• By field, date ranges, or dynamic queries
14
Solr Flare
• Ruby on Rails plugin
• facet field detection, autosuggest, saved search, inverted facets, pie charts, Simile Timeline and Exhibit integration
• Useful for rapid prototyping
• See Flare's big brother, Blacklight, for production quality

Solr Powered Library Systems
• VuFind (PHP)
• Kochief (Python)
• Blacklight (Ruby)
• and others
17
• UVA radiation = blacklight
• libraries are much more than books
• opinionated
• Ruby on Rails: best choice for an extensible user interface development framework

SolrJS
• jQuery-based interactions with Solr
• Query navigation state management and widgets
• Evolving rapidly: Drupal contributed improvements (see http://drupal.org/project/solrjs) coming soon
• Live example: http://solrjs.solrstuff.org/

Solritas
• celeritas: swiftness, speed (Latin), origin of the symbol "c" for the speed of light
• solritas: Velocity template rendering of Solr responses
• Useful for rapid prototyping and more

Food for thought
• The interface is the application
• URLs are UI too!
• Facets aren't just for lists (with counts)
• be creative: clouds, maps, graphs, etc...
• entice users to forage and browse, facilitate serendipitous discovery
