Title: Real-time search at Twitter

Abstract: Twitter’s search engine faces some of the most unique challenges in information retrieval and distributed systems today. On the scaling front, it’s a relatively young system with a massive user base, billions of queries daily, and many billions of indexed documents – with thousands being added every second. On the ranking side, the combination of realtime and social requires new solutions to relevance estimation for newly-created documents, blending different types of live content, evaluation in the absence of direct user feedback, and more. On top of this, the dynamic nature of a nascent company and product leads to a multitude of operational challenges and opportunities.
In this talk, I’ll cover some of these challenges and how we approach them at Twitter.
