@jam.with.ai: Explaining HNSW vector search in a caveman mode! In the Reel, I explained it in the simplest way: Embedding = meaning as numbers Vector = dot in space Vector DB = finds nearby meaning ANN = makes search fast HNSW = graph + layers for fast nearest-neighbor search Now the slightly more technical version: Vector search works by converting text into embeddings, which are numerical vectors that represent meaning. Similar meanings are placed closer together in vector space. So “cat”, “kitty”, and “kitten” should be closer than “car.” But at scale, checking every vector one by one is too slow. This is where ANN, Approximate Nearest Neighbor search, helps. Instead of scanning everything, it finds very close matches much faster. HNSW, Hierarchical Navigable Small World, is one popular ANN method. It builds a graph where similar vectors are connected as neighbors. It also creates multiple layers: upper layers have fewer points and help quickly navigate toward the right area, while lower layers contain more points and refine the search. So the Reel’s simple version is the core idea: Words become vectors. Similar vectors become neighbors. HNSW connects them in layers. Search follows good paths instead of checking everything. That is why HNSW is so useful in vector databases, semantic search, and RAG systems. . . .
