[Bug] Click the change answer button and will not hit the knowledge base

Problem Description

点击换个答案按钮就会无法命中知识库，如果是在输入相同问题没有出现这样的情况。

也就是说请求包含 re_chat: true 会触发该问题。

我了解到：【换个答案】该操作会换一批引用分段，生成提示词发送给模型，让模型重新回答。

Steps to Reproduce

问题：怎么办理转学？ 多次点击【换个答案】，就会出现无法命中知识库，指定回复内容。

您好，我们已经使用您提供的知识库和应用对问题做了复现，这个现象是正常的。因为按照你应用的知识库检索相似度设置，在第一次检索提问检索时只检索到了一个分段，而换个答案的逻辑是默认你对这个检索结果不满意，所以会换个分段进行回答，但是只有一个分段符合检索条件但被定义为不满意分段，所以就不引用分段，直接用上下文作为知识进行回复。您可以将知识库检索的相似度调低，只要有多个分段被检索到，在换个答案的时候就会有引用分段。

Hello, we have used the knowledge base and application you provide to reproduce the problem, and this phenomenon is normal. Because according to the similarity of the search you applied, only one segment was retrieved during the first search question search, and the logic of changing the answer is that you are not satisfied with the search result, so you will change the segment to answer, but only one segment meets the search conditions but is defined as an unsatisfactory segment, so you do not quote the segment and directly use the context as knowledge to reply. You can lower the similarity of the knowledge base search. As long as multiple segments are retrieved, there will be reference segments when changing the answer.
