Feature Request

Important Notes

I want to use a GPU in the Milvus vector database to improve search efficiency, so I hope to create GPU-based indexes, such as GPU_CAGRA, GPU_IVF_FLAT, GPU_IVF_PQ, and GPU_BRUTE_FORCE. Link: https://milvus.io/docs/gpu_index.md

However, at the moment, I see that after configuring the Milvus vector database in Open-WebUI, the created index type is fixed as HNSW. As following picture shows:

I see that the index type in the Open-WebUI source code is fixed as HNSW, as shown in the source code below:

Is it possible to specify the index type when configuring the Milvus vector database in Open-WebUI?
