How should I change the model data in the 'Create Generative Answers Node' to enable using hybrid search from Azure AI Studio?

I currently have it working for simple keyword search.

Good morning,

I hope you are doing well. in order to use semantic search, you need to add an embedding model in the Embedding Deployment Name (typically, an ADA model) and add the name of the vector field in Azure AI Search in the Vector data field. Typically, it is called contentVector.

The rest looks fine by me.
Have a great day

Good morning,

I hope you are doing well. For semantic search configuration, I went with "default". For query type, semantic are better but can be a bit unstable (resulting in a System Error). I'd start with simple, do a bunch of tests and if you are not satisfied, switch to semantic.

Have a great day.

Hi,

Thanks for your help but I think I've made an error with the model data inputs. Can you please help me out with the model data inputs here?

Copilot Studio Model data:

Azure Open AI code:
{ "data_sources": [ { "type": "azure_search", "parameters": { "filter": null, "endpoint": "'$search_endpoint'", "index_name": "pr24-yw-ofwat", "project_resource_id": "/subscriptions/f6b47df9-19c7-4fc2-95bf-2083d0029690/resourceGroups/bmaopenairesourcegroup/providers/Microsoft.MachineLearningServices/workspaces/sales", "semantic_configuration": "azureml-default", "authentication": { "type": "system_assigned_managed_identity", "key": null }, "embedding_dependency": null, "query_type": "vectorSimpleHybrid", "in_scope": true, "strictness": 3, "top_n_documents": 5, "key": "'$search_key'", "indexName": "'$search_index'" } } ], "messages": [], "deployment": "gpt-4", "temperature": 0.7, "top_p": 0.95, "max_tokens": 800, "stop": null, "stream": true, "frequency_penalty": 0, "presence_penalty": 0, "azureSearchEndpoint": "https://undefined.search.windows.net", "azureSearchKey": "***" }

Good morning,

I hopr you are doing well. Your configuration seems correct. I you use the "simple" search, you don't need to specify a semantic configuration. Everything else seems correct.

Hi Remi,

I don't get an output answer from Azure Open AI. It's only with the semantic search that 'Create Generative answers' doesn't work.

Is it something wrong with the Model data?
