We used to have this as a separate parameter, but after discussing, we realized this is completely equivalent to running search with larger k (=efSearch) and then discarding all but the desired number of hits. Given that, we chose to simplify the API in order to make it more generic and not expose this internal algorithm detail. This enables us to potentially switch to a different algorithm with different knobs without having to change the API. If you're interested in looking at the history, see Lucene90OnHeapHnswGraph ( in backwards_codecs) and you can see we used to have this `numSeed` parameter which is the equivalent to what is being asked for here. But we removed it, because we found it wasn't needed. -- This is an automated message from the Apache Git Service.
