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

• UVA radiation = blacklight

• libraries are much more than books

• opinionated

• Ruby on Rails: best choice for an extensible user interface development framework

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
