Having explored vector embeddings, database structures, and the mechanics of Approximate Nearest Neighbor search, we now focus on assembling these elements into functional semantic search systems. This chapter transitions from understanding the components to constructing the end-to-end pipelines that power intelligent search applications.
You will learn how to:
We will examine the practical steps involved in building systems that retrieve information based on meaning, contrasting this with conventional keyword matching. The hands-on sections will guide you through designing the core logic for processing search requests and returning relevant results from a vector index.
