In Best Practices for Milvus Configuration, some best practices for setting key parameters in Milvus clients are introduced to improve search performance. The index_file_size parameter affects data storage and search efficiency. Generally, increasing the value of index_file_size improves search performance but may cause large files to fail loading into GPU or CPU memory. For nlist and nprobe parameters, a trade-off between precision and efficiency is necessary when determining their values. The optimal values for these parameters depend on the dataset size and distribution.
