[Bug]: Milvus doesnt resort to Knowhere defaults

[filip-halt]

Is there an existing issue for this?

• [X] I have searched the existing issues

Environment

- Milvus version: Master  
- SDK version(e.g. pymilvus v2.0.0rc2): pymilvus master

Current Behavior

When creating an index using: { "index_type": "HNSW", "metric_type": "IP", "params": {} }

The process failes saying that efConstruction value isnt between 5,500.

Expected Behavior

The knowhere defailt config values should be used in this case instead of an error. This worked before.

The cause is from this block in indexparamcheck.

If a value is missing it shouldnt fail but rather default to HNSW config in knowhere.

Could you help confirm the milvus version and pymilvus version which resort to Knowhere defaults? It seems we always reported an error when these required parameters are not passed. /assign @filip-halt

Ah, I looked through my history and saw that it was only the search params that were defaulted to. Just tested 2.2.3-present and you are right, never supported. Might be one worth supporting.
