I wrote the book [Relevant Search](http://manning.com/books/relevant-search), created the [Elasticsearch Learning to Rank Plugin](http://github.com/o19s/elasticsearch-learning-to-rank). I'll be teaching a small class targeted at Solr & Elasticsearch developers wanting to build smarter search applications - cutting through the 'cognitive search' buzzwords. We go from TF\*IDF to boosting techniques to semantic search & machine learning (learning to rank). Here's why we created the class: > **[Why We Created Search Relevance Training](https://opensourceconnections.com/blog/2018/06/06/why-relevance-training/)** > > I love Solr and Elasticsearch, BUT… It's a great way to meet other folks working on relevance problems as well and brainstorm tough problems. A great way to get introduced to the larger relevance community. > **[Think Like a Relevance Engineer Training](https://www.eventbee.com/v/o19s/event?eid=108566992#/tickets)** > > 608 Preston Avenue, Suite 300 - Charlottesville Hope to see you there! ---

There's been a mistake here with this announcement (can't seem to find the 'delete' button). We ended up deciding Sept 25/26 are focused on _Solr_. Please [get in touch](http://o19s.com/doug) if you're interested in attending a version of this class that goes deep into Elasticsearch. If enough interest, we will build out that material. ---
