I agree with your point of setting on the page side, but there seems to be a problem with the design in the picture. If I choose the other two retrieval methods besides hybrid retrieval, top_n and top_k seem to be unable to be set.

First of all, I apologize to your team for my mistake, but this temporary solution seems to work in my project, and I also agree with @nadirvishun ‘s opinion of view. Does diffy have any plans to introduce the top_n parameter on the page side?
