Show HN: A small, crazy fast hybrid search engine written in Rust

- Lume is a new open-source search engine written in Rust that combines two search methods: "semantic" (understanding meaning via embeddings/vectors) and "keyword" (traditional exact-match). This "hybrid" approach aims to give better results than either method alone. - "Show HN" means the creator posted it on Hacker News, a tech community where people showcase side projects and startups for feedback. - Rust is a systems programming language prized for speed and memory safety — using it signals that Lume is built for high performance. - The project is from "Deep Blue Dynamics," a small company/team building search infrastructure. Their pitch: most existing hybrid search relies on slow, separate systems stitched together, whereas Lume does both in one fast engine. - Why it matters: Search is a core building block for apps (e-commerce, documentation, AI chatbots). A fast, embeddable hybrid engine could compete with heavier solutions like Elasticsearch or Pinecone for developers who need simple, local, low-latency search.
