Sure. It's actually both. When the players describe their actions, the GM has two options:
1. First, the GM can decide that the players have come up with a Good Idea. If the GM decides the players have come up with a smart approach to a problem--a smart use of their gear, spells or bodies--he or she can declare the plan a Good Idea. The players don't have to roll; it's just successful.
2. Otherwise finding hidden things like traps (or loot) or hidden characters is a Scout test. Finding things is generally a fixed obstacle (i.e., you require a certain number of successes based on how well the thing is hidden). Locating a hiding character is a versus test (your Scout versus their Scout).
In other words, if you describe looking in the right place, touching the right thing, etc. You don't need to roll. You succeed in finding whatever it is. If you simply say "we search the room" or the like, you go to the dice.
