1. Is this request related to a challenge you're experiencing?

When performing information retrieval use RAG, I hope that in addition to returning relevant content segments, the system can also return the original address of the matched files or data.
Therefore, I would like the ability to pass in the original address of the data when using the API to add data to the knowledge base.

2. Describe the feature you'd like to see

Save data to knowledge base：could pass in the original address of the data(text or file)
Retrieval：can return the original address of the matched files or data.

In some cases, If the original files are publicly accessible web pages or documents, the system can also provide the original URL links in the returned results, allowing users to directly access the sources.
