Hybrid Search with group_by: Why Is score Missing in Metadata Query?

[user_mollang]

I’m trying to perform a hybrid search and retrieve results grouped by a specific property, while also including the relevance score for each result.

To do this, I used groupBy and metadataQuery in my Weaviate GraphQL query. While the grouping works as expected, the _score is not returned in the metadata.

I’m wondering if this is a current limitation of the platform or if I might be doing something wrong in my query. Any insights or suggestions would be greatly appreciated!

hi @user_mollang !!

Hybrid search will fuse both the keywords search score and vector search distance.

So in a hybrid search, you don’t get a distance, but a score

If you are curious about what was the distance used, or how it normalized both keyword score and distance while fusing those, you can request the explain_score metadata.

Let me know if that helps!
