The "flat" binary index performs an exhaustive search. The exhaustive search is carefully optimized especially for 256-bit vectors that are quite common. The Hamming distance computations are optimized using popcount CPU instructions. Batching is applied on the query and the database side to avoid cache misses. naturwaren steffi hacke
