FAVOR: Efficient Filter-Agnostic Vector ANNS Based on Selectivity-Aware Exclusion Distances

Summary: FAVOR unifies selectivity estimation with filter-agnostic HNSW ANNS for arbitrary hybrid predicates. Its exclusion distances reshape search geometry, while selectivity-driven routing chooses pre-filtered brute force or HNSW, yielding 1.3–5× higher QPS at 95% recall.
