Tags
Extend your Finder with tags, to find your files in multiple ways.
...Well, Tags allows you to do exactly that on the mac.
Create new Tags by duplicating and renaming the Mother Tag. Drag your file or folder on top of a Tag icon to add it to that Tag. Double-click a Tag to view all items that you added to it. Remove items from a Tag by dragging them to the Trash. Or remove the Tag itself by dragging it to the Trash.
