Graph, tree, hashing, or partition-based indexes narrow the search to promising regions. Tunable parameters balance query latency, memory, and the chance of missing true nearest neighbors.
Approximate nearest-neighbor search finds likely close vectors without exhaustively comparing the query with every stored vector.
