You post seems ambiguous to me. What are the (details) of the problem with Spotlight you are having? What are you expecting to show when you type Spot?
Had the exact same problem with Spotify, AppCleaner (opens Activity Monitor), etc. Don't remember how I got rid of it though. I probably just reindexed spotlight with Onyx.
Thank you for clarifying and sorry to others, it was bad communication on my part. Yes, I find spotlight often makes very strange choices for top hit (I use Spotify a lot more than Safari, too!)
