Slides can be viewed here, as well as on Slideshare.com.

Compelling Keynotes:

  • Lucid Imagination Chief Scientist Grant Ingersoll talked about how Search is driving the era of Big Data by evolving from a matchup of queries, documents and content relationships to a more nuanced, analytics-enabled stack that leverages user interactions for improved results.

  • Twitter Search Infrastructure Technical Lead Michael Busch pushed past the frontiers of real time search, recounting how Twitter uses its Lucene search infrastructure to harness its 230 million tweets/day with 2 billion search queries, indexed in under 10 seconds, with average query response time under 50 milliseconds.
