Weird spotlight issue
I can not reproduce your problem and it is clearly not normal behavior.

So suggest for you to:

Re-index Spotlight database. It is a long process, but in background, you can keep using your computer meanwhile.


From the Apple menu, choose System Preferences.
Click Spotlight.
Click the Privacy tab.
Drag a folder or an entire volume (your hard drive) to the list. If prompted for confirmation, click OK.
Remove the item or volume you just added to the list by clicking it and then clicking the minus (“-“) button.
Close Spotlight preferences.
