As vector embeddings transform how we store, retrieve, and interact with data, building a high-performance vector search system has become an essential skill for AI engineers, machine learning practitioners, and backend developers. This book takes you step-by-step through the complete process of designing and implementing your own vector search engine, starting from fundamental concepts and progressing to production-ready architectures.

What You'll Learn:

Core Storage Strategies: Explore efficient data structures and databases optimized for high-dimensional vector data, including flat indexes, graph-based methods, and quantization techniques.
Indexing Techniques: Master inverted files, product quantization, hierarchical navigable small world (HNSW) graphs, and other state-of-the-art indexing approaches that balance speed, memory usage, and accuracy.
High-Performance Retrieval: Implement approximate nearest neighbor (ANN) search, similarity metrics, reranking, and hybrid search systems that deliver sub-millisecond query times at scale.
AI System Integration: Learn how to integrate vector search into real-world applications such as semantic search, recommendation engines, retrieval-augmented generation (RAG) for LLMs, and multimodal AI systems.
Performance Optimization and Scaling: Address challenges in distributed systems, hardware acceleration (CPU/GPU), monitoring, and maintaining relevance as your data grows.

Written with clear explanations, practical code examples in Python, and architectural diagrams, this hands-on guide emphasizes building systems that are both theoretically sound and practically deployable. Whether you're developing the next generation of search infrastructure or enhancing existing AI applications, you'll gain the deep technical foundation needed to move beyond off-the-shelf solutions.

Ideal for intermediate to advanced developers familiar with machine learning concepts who want to understand vector search at a systems level.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
