[.NET] Text Search with Vector Stores

[Daniellled]

I may be misunderstanding things, but the way I see it Semantic Kernel had two ways to use RAG, automatic, or tool call.

Automatic - This would do a search prior to agent invocation.
Tool Call - This will leave it up to the agent to decide if a search is performed.

This was accomplished two ways. With TextSearchProvider or you could use your own schema with VectorStoreTextSearch.

TextSearchProvider - This supported automatic or on-demand calls.

VectorStoreTextSearch - This appears to only support RAG via tool calling.

Agent Framework provides examples on how to do the automatic via AIContextProviderFactory. Does an example exist for the tool call version?

I think I understand a bit better after looking into the TextSearchProvider code contained within the Microsoft.Agents.AI namespace. This class appears to support both automatic and tool call versions.
