Perhaps if you bothered to explain your use-case we could suggest alternatives.
Streaming is built to handle very large result sets in a divide-and-conquer manner, thus the ability to specify worker nodes each of which handles a sub-set of the results. Partitioning the output streams requires a way to bucket the results from multiple sources to workers such that all the documents that fall into buckets can be routed to the same worker. There may be many sources (think shards) and many replicas. Score is unsuitable for such bucketing. You're simply trying to use streaming for a use-case it was not designed for. You have two choices here. > use streaming as it was intended, > use cursorMark for processing in batches.
