Apply cutting-edge machine learning techniques—from crowdsourced relevance and knowledge graph learning, to Large Language Models (LLMs)—to enhance the accuracy and relevance of your search results.
Delivering effective search is one of the biggest challenges you can face as an engineer. AI-Powered Search is an in-depth guide to building intelligent search systems you can be proud of. It covers the critical tools you need to automate ongoing relevance improvements within your search applications.

Inside you'll learn modern, data-science-driven search techniques like:

Semantic search using dense vector embeddings from foundation models

Retrieval augmented generation (RAG)

Question answering and summarization combining search and LLMs

Fine-tuning transformer-based LLMs

Personalized search based on user signals and vector embeddings

Collecting user behavioral signals and building signals boosting models

Semantic knowledge graphs for domain-specific learning

Semantic query parsing, query-sense disambiguation, and query intent classification

Implementing machine-learned ranking models (Learning to Rank)

Building click models to automate machine-learned ranking

Generative search, hybrid search, multimodal search, and the search frontier

AI-Powered Search will help you build the kind of highly intelligent search applications demanded by modern users. Whether you're enhancing your existing search engine or building from scratch, you'll learn how to deliver an AI-powered service that can continuously learn from every content update, user interaction, and the hidden semantic relationships in your content. You'll learn both how to enhance your AI systems with search and how to integrate large language models (LLMs) and other foundation models to massively accelerate the capabilities of your search technology.

Foreword by Grant Ingersoll.

About the technology

Modern search is more than keyword matching. Much, much more. Search that learns from user interactions, interprets intent, and takes advantage of AI tools like large language models (LLMs) can deliver highly targeted and relevant results. This book shows you how to up your search game using state-of-the-art AI algorithms, techniques, and tools.

About the book

AI-Powered Search teaches you to create a search that understands natural language and improves automatically the more it is used. As you work through dozens of interesting and relevant examples, you'll learn powerful AI-based techniques like semantic search on embeddings, question answering powered by LLMs, real-time personalization, and Retrieval Augmented Generation (RAG).

What's inside

Sparse lexical and embedding-based semantic search
