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).
