This book teaches you how to build a complete, production-grade local search engine that indexes diverse document types, performs hybrid keyword and semantic retrieval, powers retrieval-augmented generation with local language models, and runs entirely on your own hardware. You will move from a minimal working prototype to a feature-rich system with OCR, multimodal embeddings, incremental indexing, caching, security, and crossplatform deployment. Every code example is complete, runnable Python built on current stable releases of open-source libraries including FastAPI, FAISS, Qdrant, Chroma, sentence-transformers, Ollama, and more.
