OpenSearchCon Europe 2025

In this session, we'll delve into the critical optimizations and fine-tuning strategies that propelled HDI Germany P&C and Life Insurance, a Talanx AG subsidiary to develop a high-performance, productionized Retrieval-Augmented Generation (RAG) based GenAI solution. Leveraging OpenSearch with hybrid search, our system now empowers 300+ employees. Our journey from concept to large-scale deployment uncovered numerous minor yet powerful tweaks that significantly enhanced both, speed and accuracy of our Opensearch indexing and retrieval mechanisms. We’ll dissect the key parameters crucial for optimal RAG performance, presenting benchmarks and metrics to quantify these improvements achieved through the optimization process.

Attendees will gain practical insights into maximizing OpenSearch's potential for RAG applications, learning how to leverage these often-overlooked adjustments to achieve substantial performance gains.
Join us for an in-depth exploration of the nuances that can make a significant difference in your OpenSearch-powered RAG solutions, and leave with actionable tips to implement in your own projects.
