Spotlight doesn't show Finder
What are you trying to accomplish? Finder.app is hidden. If you wish to quickly open finder, command-tab is easy. 

If that's your goal, some of these suggestions may be helpful. Personally I use finder windows accessed via command-tab. I dragged my Downloads directory into the sidebar (it should be there already). So: command-tab to finder, click Downloads in the sidebar and viola. Alternatively, you could drag the downloads folder to the dock (it should be there already). Or, swipe 4 fingers down to reveal desktop (an option in system preferences -> trackpad), then click desktop to select finder.

In Automator you could build a workflow and save it as a service. In Automator use open finder and save as a service. This will put it in your Library to be available across applications. Then enable a quick key assigning a keyboard shortcut in system preferences -> keyboard -> keyboard shortcuts -> services.
