You can always use the command line tool xattr, which lists/reads/writes/erases the filesystem's extended attributes of a file.

That's what spotlight uses to build it's index.

Note that spotlight information keys are prefixed with com.apple.metadata:

As quick example, to change the display name on spotlight of a file:

xattr -w com.apple.metadata:kMDItemDisplayName MyNewFilename.txt ActualFile.txt


to access xattr help, type on t:

xattr -h


How can I set Spotlight metadata to files?
I'm aware that Yorick and Cho'Gath are both good counters for Jayce (in Top Lane) but who else might be a good matchup and why?
