first time trying to work with Milvus as

first time trying to work with Milvus as a vectorDB and LlamaIndex, getting this odd exception when running query_engine.query

Plain Text

pymilvus.exceptions.MilvusException: <MilvusException: (code=0, message=metric_type not found in search_params)>

I'm not entirely sure if the defaults are not set for Milvus so I set the search_params with instantiating the MilvusVectorStore but I don't think it's using it or something. Anyone ever run into this?

I wonder if milvus updated or something? You can check out the source code here

I think I finally got some success out of this:

Plain Text

# construct vector store
vector_store = MilvusVectorStore(
    uri="http://localhost:19530",
    search_config={"metric_type": "IP"},
)

for whatever reason the vector store does not have any defaults and, it uses search_config instead of the documented search_params

Very weird -- maybe make a PR if you have time haha

I had saw an issue logged about no defaults, and the bot said it was stale and closed it with the solution of "don't use default" or whatnot 🙂

LLogan M

ha the bot might close stale issues automatically, even if its still an issue (OP just never responded Im guessing)

LLogan M

If it didn't do that, there would be 10,000 issues 😆 Gotta keep it fresh at least

I'm a much bigger fan of the WONTFIX state 🙂 But, having managed many developers I understand the "head in the ground, I can't hear you" state too 🙂
