org.opensearch.index.rankeval.RatedRequest
All Implemented Interfaces:
Writeable, ToXContent, ToXContentObject
public class RatedRequest
extends java.lang.Object
implements Writeable, ToXContentObject
Definition of a particular query in the ranking evaluation request.
This usually represents a single user search intent and consists of an id (ideally human readable and referencing the search intent), the list of indices to be queries and the SearchSourceBuilder that will be used to create the search request for this search intent.
Alternatively, a template id and template parameters can be provided instead.
Finally, a list of rated documents for this query also needs to be provided.

The json structure in the rest request looks like this: 

 {
    "id": "coffee_query",
    "request": {
        "query": {
            "match": { "beverage": "coffee" }
        }
    },
    "summary_fields": ["title"],
    "ratings": [
        {"_index": "my_index", "_id": "doc1", "rating": 0},
        {"_index": "my_index", "_id": "doc2","rating": 3},
        {"_index": "my_index", "_id": "doc3", "rating": 1}
    ]
 }
