OpenSearch Optimizations for Production RAG Systems

By PulseAugur Editorial · [1 sources] ·

This article details optimizations for using OpenSearch in production RAG systems, focusing on improving the semantic retrieval step. It explains how Approximate Nearest Neighbor (ANN) search, specifically using Hierarchical Navigable Small World (HNSW) graphs, works to balance recall and latency. The piece distinguishes between index-time optimizations that build the graph and query-time optimizations that affect response speed. AI

IMPACT Provides technical guidance for optimizing AI application performance and efficiency.

RANK_REASON Article details technical optimizations for a specific software product (OpenSearch) in the context of a particular application (RAG).

    OpenSearch Optimizations for Production RAG

    <p><em>This is Part 1 of a series on optimizing OpenSearch for production RAG. Part 1 covers semantic retrieval, meaning vector search with Approximate and exact Nearest Neighbor methods. Part 2 will cover lexical retrieval, meaning text-based search and how it complements the se…
