It would be interesting to know how many actual users of COSINE there are. I agree there may be no workaround, but that does not mean we need to continue to support, either. One question I have is: if I supply normalized floating point vectors and then use quantization, does this imply that the dot-product distance is somehow broken when it is calculated in quantized space? I don't think so - we account for these issues with the correction factors. Given that, I think we can say to COSINE users -- instead of COSINE, use DOT_PRODUCT and supply your vectors as normalized floats. Or ... perhaps we could even perform the normalization during indexing? There would be some loss of precision, too bad. -- This is an automated message from the Apache Git Service.
