I put together a fairly simple workflow with my first attempt at using file filters. The purpose is to limit my search scope to an external drive. I have three keywords that can change which file filter I use to change the scope. However, when I search for files and file types that are clearly within the scope, Alfred does not return the file in the results even with the exact name. Spotlight finds the file, the file passes the Alfred troubleshooter, rebuilding the index and cache has no impact. The files are within the scope in the file filter, the file types have been added, but most of the time still fails to pull the desired result. I'm sure it is something simple I'm overlooking, but I haven't figured it out yet.
Oh, and a related issue is that I can't seem to search for files with a space in the name. As soon as I separate the file name with a space as the search term, it reverts to a generic web search. Any insights you can provide would be much appreciated.
