It seems that this should be very simple, but every attempt I have made to create syntax that will provide the desired results have failed. 

I need a search syntax to use in Workflow that will return the record folders that are part of a particular record series. I have set up an example in our development environment. In the image below, I would need my search to return the folders named 60195 and 60708 by searching for folders that are in the record series you see listed. I either get only the record series itself as a result (despite using Type="F"), not the record folders, or I get no results at all. I've tried using wildcards, using and not using the code as part of the name, etc.
