…#3095) * Add support for pre-quantized vector exact search Implement exact KNN search using pre-quantized vectors from native engines to avoid redundant quantization during query execution. This optimization retrieves quantized vectors directly from FAISS memory-optimized indexes and uses them for Hamming distance calculations.
