1. Is this request related to a challenge you're experiencing? Tell me about your story.

Currently when using knowledge retrieval node in a workflow, the multi-way retrieval is implemented even there is only one dataset, making an unneccessary second reranking. This would slow down the execution of workflow.

Suggestion:
Skip the multi-way retrieval if there is only one dataset selected.
Tips can be also added on frontend settings popup window.

2. Additional context or comments
