The blog post discusses a novel approach to improving the performance of phrase search algorithms using the AVX-512 instruction `vp2intersectq k, zmm, zmm`. It highlights the potential of early Alder Lake CPUs, which offer extensive support for AVX-512 subsets. The author praises the post's depth and the challenges overcome in the development process. However, some commenters question the efficiency of recursion in the algorithm, critique the merging strategy for tokens, and emphasize that different data structures like suffix arrays could enhance efficiency further. The discussion also touches on confusion regarding the algorithm's pre-computation versus on-the-fly processes, along with the representation of token positions and the role of roaring bitmaps for intersection operations.
