The Facebook Search Bar/ Stalking?

So i'm not friends with my ex on Facebook and I read that the first name that comes up is like who's looking you up, I searched the first letter of his name and he came up, I put in his middle initial, he came up, I put in the letter of his last name, he came up.
I find that I find my exes in the search bar even when I don't look at their profiles
A friend is friends with my ex (a different ex) and when I search my friend, my ex comes up and were not friends either.

Is this a real thing?
Yeah, sounds right
No I think you're thinking things
Maybe, probably not
This is true
This is not true
