Editor's top Vector Databases books
2LLM Engineer's Handbook
Paul Iusztin, Maxime Labonne · Packt · 523 pages · ~13 hrs to read
The most complete treatment of vector databases in a production LLM context — covers embedding generation, vector store integration, RAG pipeline design, and evaluation as part of a full LLM engineering workflow.
Relevant Search
Doug Turnbull, John Berryman · Manning · 541 pages · ~14 hrs to read
The best book on why search results rank the way they do — written for Solr/Elasticsearch but the relevance-tuning mental model (query understanding, boosting, signal blending) applies directly to hybrid dense/sparse retrieval in modern vector stacks.

AI-Powered Search
Trey Grainger, Doug Turnbull, Max Irwin · Manning · 518 pages · ~13 hrs to read
Covers semantic search architecture in depth — including dense retrieval, sparse retrieval, and hybrid approaches. The deepest technical treatment of the retrieval problem that vector databases solve.

Introduction to Information Retrieval
Christopher Manning, Prabhakar Raghavan, Hinrich Schütze · Cambridge University Press
The classical IR textbook that every modern vector search technique is built on top of — inverted indexes, tf-idf, vector space models, evaluation metrics. Dense embeddings changed the representation, not the underlying retrieval theory this book teaches.
Natural Language Processing with Transformers, Revised Edition
Lewis Tunstall, Leandro von Werra, Thomas Wolf · O'Reilly · 430 pages · ~11 hrs to read
Written by Hugging Face engineers — explains where embeddings actually come from before you store them in a vector index. Essential if you want to understand what you're embedding, not just which SDK call to make.
Deep Learning for Search
Tommaso Teofili · Manning · 502 pages · ~13 hrs to read
Covers neural ranking, document embeddings, and cross-language search built on top of Lucene-family engines — a useful bridge for engineers coming from traditional search infrastructure into embedding-based retrieval rather than starting from a blank LLM tutorial.
