What would you like to be added?

Metric_type like 'L2'/'IP' does not need to be specified in search params, we could infer the metric_type from index side.

Why is this needed?

Totally agreed. now seems that index is a must there is no meaning for search. Just ignore it when user specified metric type on search for compatibility
