Describe the feature you'd like

sometimes I need retrieval chunks for GPTs schema usage. But default api for retrieval returns all the chunks found. please and top_n for this api.

    top_n = req.get("top_n")
    if top_n and isinstance(top_n, int) and top_n > 0:
        ranks["chunks"] = ranks["chunks"][:top_n]

thanks!
