Support for RAG with Q&A Model via Connector. Currently we can do RAG only with text generation models

I am using Q&A model for RAG
The Q&A Model takes two inputs as question and context

{
		"question": "where live??",
		"context": "My name is Clara and I live in Madrid."
}

While doing neural search how i will pass the parameter for question and context
Where should i add the context? Or utilizing two paramters is not possible in OpenSearch RAG?

{
    "query": {
        "neural": {
            "neural_field_vector": {
                "query_text": {{question}},
                "model_id": "90tQBI0BCjm4TK7_mz2B",
                "k": 1
            }
        }
    },
    "size": 1,
	"_source": [ "neural_field"],
    "ext": {
        "generative_qa_parameters": {
            "llm_model": "bedrock/q&a model",
            "llm_question": {{question}},
            "conversation_id": "eHFSxIwBu3N8jyGnExM0",
            "context_size": 5,
            "interaction_size": 2,
            "timeout": 15        }
    }
}

question and answer is not part of my document/index records. Only neural field is part of my document which is vectorized with neural_field_vector.
When i do neural search by asking question it gives the response of neural_field now the question that i will ask to neural search will give the response of neural_field which is working perfectly.
Now this same question should go to my LLM as question and the neural_field which came as a response from neural search should map with the context .
In llm RAG i do not have the mapping ways, all i have is context_field_list
which is part of document and not the LLM parameter.

We need to support this, there can be multiple parameters in the models as model advances.

@mingshl could we solve this with a generic ml search processors?

for the ml inference search processors, yes, it can use the QA model to achieve the QA search. the generative_qa_parameters can be put in the model_config parameters in the inference processors.

for example,

{
  "description": "test ml model search request processor",
  "processors": 
  "response_processors": [    {
      "ml_inference": {
        "model_id": "90tQBI0BCjm4TK7_mz2B",
        "model_config":{
           "generative_qa_parameters":{
                 "conversation_id": "eHFSxIwBu3N8jyGnExM0",
                "context_size": 5,
                "interaction_size": 2,
                "timeout": 15    }
              }, 
        "input_map": [
          {
            "query_text": "llm_question",
            "neural_query_result_field": "context"
          }
        ],
        
        "output_map": [
          {
            "llm_response": "answer"
          }
          
        ]
      }
    }]
}

users can pipe up search request processor, either using ml_inference search request processors or text_embedding_request processors, both should work
then user should be able to use standard neural queries, the context will be a

{
    "query": {
        "neural": {
            "neural_field_vector": {
                "query_text": {{question}},
                "model_id": "90tQBI0BCjm4TK7_mz2B", //<text_embedding_model_id >
                "k": 1
            }
        }
    }
