What is your question?

I want to use the sift data set to test different search methods in milvus, such as "index_type": "IVF_FLAT", "metric_type": "L2". But the recall rate achieved so far is always 0. Is there anyone who has done this before? Can you help me answer it?I need relevant python code to test milvus performance using sift dataset.

Anything else?
