Can you remove searches on Facebook?

This is probably impossible and a really dumb question but here goes.

You know when you're on Facebook, and you go to search for people or pages, and as you're typing, the results start to come up and the ones at the top are people that you search a lot?
For example, when I type in "K", my sister is at the top (whose name starts with a "K").
So I'm wondering, is there any way to make it so someone stops popping up at the top? Every time I type a certain letter, my ex's name pops up first but I haven't gone to his profile in a long time and I'm sick of him popping up, we're not even Facebook friends anymore.

Sorry if this is dumb or confusing. It would just be convenient to get rid of this.
