RA (without G) Feedback

Hi. I’m creating an app for searching information on a project documentation. It is working similarly to a RAG app, but without the generation part: it chunked the data, created the embeddings and indexed them, and when the user ask for information, the app give back the relevant documents (the ones which have the “best” chunks).
I need to get feedback to improve the app, but I don’t know how to do it. Do you have any ideas?
