Alexander Reelsen and Britta Weber from elasticsearch will join us. Alex will talk about "What's new in Elasticsearch?" and Britta will talk about "The Significant Terms Aggregation".

Whats new in Elasticsearch? by Alexander Reelsen

Elasticsearch is moving fast! Every release is packed with new features or important bugfixes, and it can be hard for users to keep up. This presentation will explore the latest and greatest features of Elasticsearch. Alexander Reelsen, one of the Elasticsearch developers, will guide you not only through these features but also explain the rationale behind the development decisions. And, instead of looking only at past releases, we will also take a look at whats coming next!

The Significant Terms Aggregation by Britta Weber

Significant terms aggregation is a feature that allows to identify terms that are relevant to a particular set of documents. Relevance here does not only mean how often a term occurs but how much more often a term occurs in the set compared to the whole document collection. I will briefly explain how "significance" is measured here and show some usecases for this type of aggregation.
