The author built a web search engine from scratch in two months using 3 billion neural embeddings, with the goal of creating a better search engine that can understand intent and provide high-quality results. The search engine uses a combination of natural language processing and machine learning to index and retrieve web pages. The author discusses the challenges of building a search engine, including handling noise and irrelevant content, and presents a high-level architecture of the system. A live demo of the search engine is available.
