Spotlight: Search flagged Mail Messages I'm looking for a way to have all mail messages flagged/labeled with "Red" show up in a saved search in the Finder, but Mail.app flags doesn't seem to be indexed by Spotlight. 

Any ideas?

You can search for tags in Spotlight using the following syntax:

tag:name


For example, to search for all messages with Stack Exchange that are tagged Red, do:

Stack Exchange tag:Red
