IVF-PQ index: inverted file with product quantization.

kmeans

k-means++ seeding and Lloyd iterations for the IVF coarse quantizer.

params

IVF-PQ index parameters.

search

IVF-PQ search: probe the nearest cells, rank their entries by PQ distance, and rerank the best of them by exact FP32 distance.
