code4lib 2011 preconference, presented by Erik Hatcher of Lucid Imagination.
Abstract: The library world is fired up about Solr. Practically every next-gen catalog is using it (via Blacklight, VuFind, or other technologies). Solr has continued improving in some dramatic ways, including geospatial support, field collapsing/grouping, extended dismax query parsing, pivot/grid/matrix/tree faceting, autosuggest, and more. This session will cover all of these new features, showcasing live examples of them all, including anything new that is implemented prior to the conference.
Clipping is a handy way to collect important slides you want to go back to later.
