Hello, I have a question, does NGT support InnerProduct as distance function? I dont see IP function when use float as datatype. If it does support IP, have you test the performance using IP as distance function? Compared to Hnsw?

Hello, I think that you mean maximum inner product search (MIPS). NGT does not support MIPS.

55 might be helpful.
