Is your feature request related to a problem? Please describe.
OpenSearch will error "cannot usecollapse in conjunction with rescore", if I have both collapse and rescore clause in the query. In ecommerce space, my existing query rely on collapse (collapse on the same parent ID) to deduplicate the same variations of a product. Because of the limitation, I cannot use learn to rank plugin which need rescore to re-rank to improve my search relevancy.

Describe the solution you'd like
No error issues when using collapse in conjunction with rescore. And rescore should happen first to ensure the correct ranking of the face out item.

Describe alternatives you've considered
N/A
