Thanks for your reply, Vítor.
I did read some portion of the two posts you've mentioned, but I can't see how I can access these <title></title> <subtitle></subtitle> attributes for using them in, say, a workflow that takes the title and subtitle of my example and formats them in a markdown link and copys them to my pasteboard. I don't need to put stuff in my results that is not already found by the file filter, I want to use the info that is found and shown in the results. Maybe I've overlooked something, but it seems to me, that the two posts answer the question of how to get stuff in the results, whereas I want to accomplish the opposite.
