This one is actually easy. Most commonly, orange is a color and a fruit. I'm sure we can all pretty easily list some objective facts about both of those things.

Orange is also the name of a town in some places, and a county in others. But I think you need more search terms in order to disambiguate. The search engine can't read minds, after all.

Maybe the user was actually looking to pay their phone bill? (The first result in DDG is orange.fr, not the color or the fruit)

My point is, there's no objective way to determine what good search results are. There are thousands of different objective measurements which people combine in subjective ways to create a subjective algorithm.
