Labels for files

Is there a way to add labels to files so I can in turn search for files based on these labels? Basically trying to link files to the user that uploaded them. I would prefer not to create different buckets for different users.

I dont belive so the way you want. You can create a collection with a document for each file that has the fileId and the label you want for that fileId then you can search the documents for the label then get the fileId and search the bucket for that ID
