Hybrid Search Score Normalisation

[gauravsingh]

I wanted to understand how open-search score normalisation works with hybrid search query.

In this reference (Hybrid search - OpenSearch Documentation ), as I can see even though normalization is applied with weight of 0.3 and 0.7 stills I see

 "max_score" : 1.2251667

In the final response of hybrid query search.
How even is this possible if score normalisation is done, and still max score is greater than 1.0?

Could someone explain what I missing here?

@gauravsingh so what normalization you are using? Are you using min-max or L2?

Also if possible can you provide your query and I can see if normalization is happening or not.

Thanks for the reply, I am looking at the same example mentioned here Hybrid search - OpenSearch Documentation
