OpenSearchCon India 2025

OpenSearch is a powerful tool for log storage, analysis, and dashboard reporting. In the context of Retrieval-Augmented Generation (RAG) applications with Large Language Models (LLMs), OpenSearch serves as a vital component, acting as a vector database. This presentation explores an architecture and process flow to integrate graph-based context with OpenSearch, enhancing the correlatability of data and improving the context and performance of search results.

Through experimentation with synthetic data from a travel app, we’ll demonstrate how customer activity data—such as travel points, preferences, and interactions with destinations—can be integrated into OpenSearch. By introducing graph points and correlating them with other data (e.g., maps and historical data), we can provide personalized, more relevant search results for users. Additionally, we’ll compare metrics before and after the introduction of graph context to showcase how it improves search performance and the overall user experience in RAG-based systems.
