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

We now have a unified business knowledge base platform. We perform searches based on Dify's vector knowledge base. We have a large number of documents on Dify, so we hope that Dify can use metadata for filtering when directly searching the knowledge base, which can significantly improve the search speed and effect.

@JohnJyong Hello, I have read the latest code of Dify. It already supports metadata filtering when retrieving external knowledge bases. Will Dify's internal knowledge base search API retrieve this recently?
