The knowledge base needs to be able to add custom fields and use them for filtering in workflow knowledge retrieval, which would be a particularly useful feature

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

When I call a workflow, I need to filter specific data in the knowledge base in different scenarios. However, currently dify can only retrieve information from the entire knowledge base. I have to create multiple knowledge bases and workflows. But this will be a huge workload.

Thank you for your valuable request. Adding Metadata to the knowledge base data may solve your problem. We are investigating internally. This part of the functionality is on the knowledge base product planning roadmap.

我也需要这个功能，非常需要。请问大概什么时候能上线该功能，根据不同的用户，我应当检索不同的数据集（或者说我可以根据我附带的变量选择某个数据集筛选出满足某些字段的数据）

@takatost, the user @christophersandmann has indicated that this issue regarding adding custom fields to the knowledge base is still relevant. Could you please assist them with this?

I'm facing the same issue. My workaround is converting the filter object into a string, then merging it into the user query. When the Knowledge Base retrieves it, the backend will split and parse the filter object
