Hi, if the text inside the chunks is the same, it’s reasonable to expect that the two will have the same vector.
I’d like to know a bit about your environment. Are you using Dify Cloud, or are you self-hosting Dify? Which embedding model are you using? If you’re self-hosting, which Dify version and which vector database are you using?
It also seems like the other post is behaving in a counter-intuitive way.
Since I can’t reproduce the issue in my environment, there might be some kind of inconsistency in the data within your vector database.
Could you try creating a new knowledge base from scratch, upload the same document, and see if the issue still occurs?
