They stack, but you can double up on help by hiring a friend to help with a charged location.

The time limit before you can re-hire that friend can be reset by TTing. It costs nothing to hire. So I hire for every location I play.

If I hire a person with the same badge as the top charge, I get a double charge benefit. If I hire someone with a different badge, I get two different benefits (say lower energy plus more coins both on the same search).

You can preview just how much you will get after clicking the location but before starting the search at that location.
