Currently, in my own project, I am also using similar environment variables to simply distinguish between topK and topN. However, a better approach would be to differentiate them on the knowledge base configuration interface (and also add a threshold parameter), rather than handling it through coding.

Yes, this is only a temporary solution for users with a rag background. Adding relevant parameters on the page side would involve product design, so we have not made any relevant modifications.
