Currently, there is no way to tell where the search results in spotlight search came from without opening the searched object. In the context where users already have the luxury of seeing the preview of the search results, it would be a great convenience if the user could tell the file location instantly. This comes even more handy when search result produces non-unique results. Wouldn’t that be a small enhancement for a great purpose?
I have submitted the feature request to Apple OSX team. Let’s see if they hear me.
