推荐的方法是创建一个RetrievalQA然后将其作为整体Agent中的工具来使用。让我们在下面看一下如何实现我们可以使用多个不同的vectordbs将Agent作为它们之间的路由器。有两种不同的方法可以实现这一点
让Agent像正常工具一样使用vectorstores设置return_directTrue来将Agent真正用作路由
创建VectorStore

I need to find out the advantages of using ruff over flake8
Action: Ruff QA System
Action Input: What are the advantages of using ruff over flake8?
Observation: Ruff can be used as a drop-in replacement for Flake8 when used (1) without or with a small number of plugins, (2) alongside Black, and (3) on Python 3 code. It also re-implements some of the most popular Flake8 plugins and related code quality tools natively, including isort, yesqa, eradicate, and most of the rules implemented in pyupgrade. Ruff also supports automatically fixing its own lint violations, which Flake8 does not.

如果我们打算将Agent用作路由并且只想直接返回RetrievalQAChain的结果我们还可以设置return_directTrue。
需要注意的是在上面的示例中Agent在查询RetrievalQAChain之后还做了一些额外的工作我们可以避免这样做直接返回结果。

由于vectorstores可以很容易地作为Agent中的工具使用因此可以轻松使用现有的Agent框架回答依赖于vectorstores的多跳问题。
