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

When searching in the RAG knowledge base, it is hoped that filtering by document name will be supported. This way, when using API integration, the specified version of the document can be queried by passing in the document name.

知识库检索时，希望能支持根据文档名称进行筛选过滤。这样在使用API对接时，通过传入文档名称查询指定版本的文档

Retrieval can also be performed through metadata.
