search a set of vectors, that are pre-quantized by the IVF quantizer. Fill in the corresponding heaps with the query results. search() calls this.

@param n nb of vectors to query @param x query vectors, size nx * d @param assign coarse quantization indices, size nx * nprobe @param centroid_dis distances to coarse centroids, size nx * nprobe @param distance output distances, size n * k @param labels output labels, size n * k @param store_pairs store inv list index + inv list offset instead in upper/lower 32 bit of result, instead of ids (used for reranking).
