Local RAG, Prompt Template

[colegero]

I don't understand how to implement the following in Flowise:
I vectorized a CSV file where column A contains the question "How to add a user," and column B contains the category "Access Management Service" and so on. Next, I obtained a structure of vectors and saved it in a local directory on my PC. Now, how do I configure the nodes for RAG chat so that if you type a question like "How to add a user" in the chat, the response simply returns the category "Access Management Service," meaning that similar questions by meaning from column A should be identified and the corresponding category from column B should be displayed.
