To follow what Tarantula said, what if you have a 25x25 room with a desk and a bed and 5 inches of junk all over the place. You can't see the ground.
There is a hidden magical longsword under the mattress and a bag of gems in the 2nd drawer of the desk. On top of that, there is some valluables mixed in the junk like a magical ring and a ioun stone. The desk is trapped with a poison needle and some nasty little gremlin installed a magical trap in front of the bed. Logically, a 3.5 adventure would require a search for every single 5x5 squares and comparing the results with the DC of each items hidden and the traps... you find or you don't.
But how is it deal with in Pathfinder ?
The same ? Or is it only one perception check comparing the results with each DCs and adding modifiers for distance and other modifiers ?
