OpenSearchCon Europe 2026

Agents and AI systems require answers that are reliable, precise and fast. In enterprise and organizational environments, these answers also must be secure. In fact, vector databases and search engines provide rapid access to knowledge. But a key challenge remains: how to correctly apply the permission models of underlying content sources within hybrid and semantic search workflows?

This presentation outlines how organizational knowledge can be securely integrated into OpenSearch. We will walk through how permissions need to be modeled, how authentication can be applied, and how these constraints propagate through the search and retrieval pipeline. In addition, we will show how prompt and query preprocessing can improve reliability and precision, particularly for agentic and AI‑driven use cases.
