Block WAND works by maintaining an upper bound on how much score any document within a block of document IDs could possibly achieve. As the engine fills its Top K heap, it establishes a threshold: the lowest score currently in the heap. Before evaluating a block, the engine checks the block’s maximum score. If that maximum is below the threshold, the entire block is skipped without scoring individual documents.
