At its heart lies vector similarity search, where high‑dimensional embeddings capture the meaning of text, images, or audio, and the system finds the nearest vectors to a query. ...

Introduction Over the past few years, the rise of embeddings—dense, high‑dimensional vectors that capture the semantic meaning of text, images, audio, or even code—has transformed how modern applications retrieve information. Traditional keyword‑based search engines struggle to surface results that are semantically related but lexically dissimilar. Vector search, also known as approximate nearest neighbor (ANN) search, fills this gap by enabling similarity queries over these embeddings. Building a vector search engine that can handle billions of vectors, provide sub‑millisecond latency, and remain cost‑effective is no small feat. The challenge lies not only in the algorithmic side (choosing the right ANN index) but also in distributed data management, fault tolerance, and horizontal scalability. ...

By coupling a retriever (often a vector‑search engine) with a generator (the LLM), developers can answer queries that go far beyond the static training data of the model. ...
