Is it possible to use two data sources or indexes in Semantic Kernel?

[Cobra86]

I am trying to use two indexes in a single Azure AI Search instance. I attempted to add two extensions, but I keep receiving an error indicating that only one data source can be defined.

Is it possible to use two data sources or indexes in Semantic Kernel?

The limitation of the current connector is you can only have one data source with AzureAISearch

@Cobra86 , when you say two extensions, do you mean the Azure Open AI Service /extensions API with dataSource parameter?

I am wondering is it better to just use the generic /completions API and inject the Azure AI Search retrieval content manually?

Since index is configured on per-request basis, I think it should be possible to use multiple indexes for different requests:

semantic-kernel/dotnet/samples/Concepts/ChatCompletion/AzureOpenAIWithData_ChatCompletion.cs

Lines 50 to 55 in 8033515

	var chatExtensionsOptions = GetAzureChatExtensionsOptions();
	var promptExecutionSettings = new OpenAIPromptExecutionSettings { AzureChatExtensionsOptions = chatExtensionsOptions };
	var chatCompletion = kernel.GetRequiredService<IChatCompletionService>();
	var chatMessage = await chatCompletion.GetChatMessageContentAsync(chatHistory, promptExecutionSettings);

But I'm not sure it's possible to specify multiple indexes as part of one request.

I was able to switch between two different Azure AI services at runtime, but I was doing it manually, allowing the user to toggle between the services.

I'm not sure if it's good practice to create Kernel plugins and then call chatCompletion.GetChatMessageContentAsync within the plugin function.

Also, I can't use Azure AI search extension and kernel plugins together.

This is a known limitation:
https://github.com/Azure/azure-sdk-for-net/tree/49b0ace48d35cb4b2ace93b517036b660fc12ca4/sdk/openai/Azure.AI.OpenAI#use-your-own-data-with-azure-openai

NOTE: The concurrent use of Chat Functions and Azure Chat Extensions on a single request is not yet supported. Supplying both will result in the Chat Functions information being ignored and the operation behaving as if only the Azure Chat Extensions were provided. To address this limitation, consider separating the evaluation of Chat Functions and Azure Chat Extensions across multiple requests in your solution design.

Thank you.
