Hey @GarrettCox. 
Thanks so much for your post!
Are you hoping to search file names from Bluescape Home and return all associated workspaces that contain that file? Currently, the Search from Bluescape Home pertains to workspace names, not files contained within the workspace.
More info about workspace search results from Bluescape Home can be found here: Overview of Bluescape Home
From within the workspace, you can search file names to bring up the files you’re looking for.
I can understand why you are looking for this solution. This is valuable feedback to pass along to our product team for how we can improve the Search feature from Bluescape Home.
