This talk was given in January 2013 at the Chicago Enterprise Search Meetup meetup.com/Enterprise-Search-Chicago/, hosted at Spantree's office in the West Loop.
It was co-presented by Cedric Hurst and Gary Turovsky of Spantree Technology Group, LLC spantree.net.
We cover the basics of the Elasticsearch APIs, mostly through examples of mapping, indexing and querying via a cURL-based REPL written specifically for the presentation.
