The Knowledge Engine: Building RAG Systems: Retrieval-Augmented Generation with Python and Vector Databases

By: Boozman, Richard

LLMs are powerful.
But without the right data, they are limited.

Retrieval Augmented Generation, RAG, transforms AI systems by combining language models with external knowledge sources, enabling accurate, context aware, and up to date responses.

"The Knowledge Engine" is a practical, hands on guide to building RAG systems using Python and modern vector database technologies.

This book shows you how to design intelligent systems that retrieve, reason, and generate with precision.

Why RAG is essential for modern AI

Standalone models struggle with:

outdated knowledgehallucinationslack of domain specific contextlimited accuracy in complex queries

RAG solves these problems by integrating retrieval systems with generation models.

With RAG, you can:

connect AI to real data sourcesimprove accuracy and relevancereduce hallucinationsbuild domain specific AI systemscreate scalable knowledge driven applications
What you will learnfundamentals of retrieval augmented generationhow vector databases workembeddings and similarity searchbuilding retrieval pipelinesintegrating LLMs with external datachunking and indexing strategiesoptimizing retrieval performanceevaluation and improvement of RAG systemsscaling and deploying RAG applicationsmonitoring and maintaining knowledge systems
From documents to intelligent systems

Throughout the book, you will learn how to:
