Create a Smart Folder based on an EXIF keyword? How can I create a Finder Smart Folder based on an EXIF keyword?

I confirm that the EXIF keyword exists using exiftool. For example, I added the keyword "Mango" to an image and created the Smart Folder like so:


Open a Finder window
New Smart Folder
Click the Plus icon
Change Name to Keywords
Next to Matches I type Mango
Click Save
Save it in the default location (~/Library/Saved Searches)
Click the Mango Smart Folder in my Sidebar but it returns no results


How can I create a Finder Smart Folder that searches the files' EXIF keywords?
Note this works for .jpg images (not .png).


Open a Finder window
New Smart Folder
Click the Plus icon
Change Name to Other
Search Raw
Click Raw query and OK
Next to Raw Query type "kMDItemKeywords = Mango"
Click Save
Name the saved search and save it in the default location (~/Library/Saved Searches)
Click the Mango Smart Folder in the Sidebar and see your result
