Expected Behavior

No response

Steps To Reproduce

from langchain.vectorstores.milvus import Milvus

self.milvus = Milvus(embedding_function=EmbeddingsFunAdapter(self.embed_model),
                             collection_name=self.kb_name,
                             connection_args=kbs_config.get("milvus"),
                             index_params=kbs_config.get("milvus_kwargs")["index_params"],
                             search_params=kbs_config.get("milvus_kwargs")["search_params"],
                             auto_id=True
                             )

Anything else?

index_params and search_params The configuration file is IP （or COSINE），Only two metric L2 will work.

Has this bug been fixed?I had the same problem.
pymilvus 2.4.8
milvusdb/milvus:v2.4.5 docker

[zc277584121]

@wuqi930907
from langchain.vectorstores.milvus import Milvus is outdated,
you can use the langchain_milvus to get the latest langchain milvus integration update

pip install -U langchain-milvus

from langchain_milvus import Milvus

[wuqi930907]

@zc277584121
Thanks, but I still have problems.
Following is my code:

`from langchain_milvus import Milvus
from langchain_huggingface import HuggingFaceEmbeddings

embedding = HuggingFaceEmbeddings(model_name="./TencentBAC/Conan-embedding-v1")

vecs = Milvus(embedding_function=embedding,
connection_args={"host": "127.0.0.1", "port": 19530, "db_name": "default"},
collection_name="AI")

search_parameters = {
"metric_type": "COSINE",
"params": {
'nprobe': 10,
'level': 1
}
}

query = "llama3中做了哪些模型架构方面的修改"
data = vecs.similarity_search_with_score(query, 4, param=search_parameters)
print(data[0][1])`
