Abstract
"Agent Builder: Providing Relevant Context for Data Driven Agents"

What are agents? What is context engineering? Join us as we dive into the importance of context engineering for providing relevant information to agents, and how to build grounded agents using Elastic Agent Builder.

"Improving Search Ranking with LambdaMART and Elasticsearch"

Quizlet’s search extended manual Elasticsearch boosts with a Learning-to-Rank (LambdaMART) model. Using query, engagement, and content features, we trained on study signals and validated with A/B tests, achieving measurable lifts in study rates: +3.42% on blended pages, +1.86% on sets pages, and +1.05–1.81% in downstream outcomes. This talk shares how we combined a custom ML re-ranker with Elasticsearch results—covering training data design, offline evaluation, latency, and model interpretability—and offers guidance for Elastic users to go beyond boosting and improve ranking quality.
