An anecdote on MacOS Spotlight and learning algorithms: I never started Chrome browser with it, because it was already running and never shut down. Then I (once!) started the chess game with Spotlight. Fast forward half a year, and Firefox had became my preferred browser. Chrome was no longer running always. However, Every Single Time I now try to start Chrome using Spotlight this happens: Type 'C', press enter and Chess starts up. Shut down Chess, carefully type 'Ch' and wait for Chrome to appear on the list.
