@nemolig 看起来是请求LLM时参数太长了，知识库有设置了召回文档数量吗？

[nemolig]

没有设置，是自动计算的，使用的模型是qwen-turbo，知识库中只有一个800KB的pdf文件

[moyangzhan]

@nemolig 初步判断是携带的历史记录太多了，可以先把AbstractLLMService.ragChat方法里的maxMessages(6)里的值改小点，比如说改成maxMessages(2)，过几天我再提交一个好点的版本，可以自动判断应该携带多少条历史记录。

还有个建议，就是好像没有清空知识库聊天记录功能，每次进页面都自动加载历史，能不能手动清除呢

@nemolig 功能加上去了，需要重新拉下前后端的代码
