Add missing weight parameter documentation for Weighted RRF retriever and update elasticsearch-specification #136477
Description
The new weight attribute introduced as part of the Weighted RRF retriever (GA’d in #130658) is currently not documented in the REST API reference and not reflected in the elasticsearch-specification TypeScript definitions.
Details:
Docs page missing update:
RRF Retriever REST API Reference
The page still refers to “equally weighting” retrievers and doesn’t include the new weight field in the retriever container examples.
Specification type missing:
In _types/Retriever.ts, the RRF retriever definition does not include an optional weight property for each retriever container.
Relevant PR introducing feature:

Action Items:
Update RRF retriever docs to include:
- weight parameter in the retriever container schema
- Example JSON usage with weighted retrievers
- Updated language removing “equal weighting”
Update elasticsearch-specification to include: - weight?: float;
in the RRF retriever container definition.
