The search box has become the de-facto “user interface” for interacting with data in the modern era. Virtually every website, app, and modern software interface relies upon or could benefit heavily from relevant search, and the Apache Lucene/Solr open source search project is the most deployed solution for delivering search across today’s top companies.
Come learn how to add automatically-learning and highly-relevant search to your applications from Trey Grainger, author of the books AI-Powered Search and Solr in Action and recognized industry expert in building intelligent search applications. You’ll learn how to use the Apache Lucene/Solr project to implement AI-powered search, though most the techniques learned in this workshop will also be applicable to other modern core search engine (Elasticsearch, Lucidworks Fusion, Open Distro for ES, Vespa, etc.)
This workshop assumes no prior knowledge of Lucene/Solr (we’ll provide an overview in the morning session), and we will approach learning from a capabilities and relevancy standpoint that is ideally suited for data scientists and application developers looking to implement intelligent features in their software (keyword matching, machine-learned ranking/learning to rank, word embeddings and dense vector search, personalized search, recommendations, semantic search, smart autocomplete, etc.). More technical product managers interested in these capabilities will also find this workshop quite helpful.

● Question / Answer Session on topics relevant to the attendees
Who should Attend?
● Data Scientists, Software Developers, and Product Managers interested in learning about information retrieval and how ML and AI can drive contextual, domain-aware, personalized results to users of search-driven applications
● People looking for an introduction to Apache Lucene/Solr, the most widely used search engine technology on the planet. Note that many of the concepts in the training also apply to other search engines, such as Elasticsearch, Lucidworks Fusion, Open Distro for ES, and Vespa, but this training and associated labs will target Lucene/Solr.
● Attendees will not be required to write code, but the workshop will contain labs that the instructor will walk through while attendees follow along. Programming knowledge, as well as familiarity with REST and HTTP, are needed if you want to go beyond the concepts and get hands-on experience with the labs yourself. The labs will primarily be implemented in Python in Jupyter Notebooks in order to appeal to both software developers and data scientists and to enable all attendees to easily follow along.
Who should NOT Attend?
Those looking for a detailed training on DevOps with Lucene/Solr or a deep dive into Lucene/Solr under the hood. This course is instead primarily focused on relevant search and automating the process of creating relevant search though machine-learning and feedback loops.
