   i dont agree, I think the problems are flaws with the HNSW and can't be 
worked around. Its too slow already at 768 and in fact the current limit 
overpromises and underdelivers by allowing you to even do this.

   Please don't do this. If somebody is not able to reduce the number of 
dimensions before indxing the stuff heshe should also not use vector search at 
all because it will just produce huge indexes that are slow like hell. If you 
understand your data you can also reduce dimensions. If not, it is the wrong 
tool for you.

   Neither of you are wrong. In this case, we have a world of people excited 
about a new thing, willing to take actions that go against science because 
vendors have told them it is right. While I am personally confident that the 
number of dimensions that is useful for the search use case ought not exceed 
768, ithe hard and fast rule boxes us out a fabulous amount of explorational 
compute. I never want Lucene to be perceived as legacy software. 
   
   
   On this point, I will stand down, especially because if users want to change 
they can. We’re open source. Reliability and performance of the unchanged 
system are more important.
