ACORN: Performant and Predicate-Agnostic Search Over Vector Embeddings and Structured Data

Summary: ACORN: hybrid ANN + structured search over embeddings/attributes with predicate-agnostic support. Key idea: predicate subgraph traversal on HNSW, implemented as a drop-in extension, yielding state-of-the-art throughput/recall across simple and complex mixed-modality queries.
