Maybe you can help me a little further. I am trying to create a workflow like you've explained, but I'm not sure how to replicate the way Alfred searches for Documents by default. Using the filter without any file types specified is, understandably, just like searching with the "open" keyword. However, I don't know what specific file types Alfred searches for with the Documents box checked, so I'm not sure what file types to specify in the File Filter. Do you have any advice?
Thanks so much.
