WoW: A Window-to-Window Incremental Index for Range-Filtering Approximate Nearest Neighbor Search

Summary: WoW: a window-graph RFANNS index that incrementally inserts vector–attribute pairs into hierarchical variable-size windows and uses range-selectivity–aware relevant-window pruning to reduce attribute checks and distance computations. Matches best static query latency, 4× faster than prior incremental indices, builds as fast as the fastest builder and uses 0.4–0.5× space. (summarized by gpt-5-mini on Feb 11 2026)
