Hopefully developers can add a parallel search mode

I know you added Template Placeholders,But for someone like me who doesn’t know how to program, it’s too hard (or maybe I’m too lazy to learn a new skill that’s a bit of a hassle).
So what I’d like you to do is put a plus sign behind the search button that you can add to indefinitely, and when I click the plus sign, I’ll add a search box that will coexist with the first search box, so that I can search for age and gender at the same time, without having to search for age and agonizing over their gender
