Why is my own data least important in search?

All across macOS and iOS, when you search for something, the ordering of results in most cases is:

• A top hit (unclear how this is generated)

• Suggestions (unclear how this is generated)

• Your own data that you spent valuable time entering

Maps

I’ll provide several examples. First up, Maps. Let’s say I want to search for my doctor in Maps. She is in my Contacts.

Contact card.

Let’s start with a search for “se” just for grins. Note how we have a Top Hit, Suggestions, and then my own data at the bottom.
