I gues I never gave it too much of a read. I use Spot for rective things, with synergy, and Search for active. Listen for trying to actively make out sounds and Spot for noticing them.
I guess if you house ruled it you would just seperate what I would call "Perception Checks" into something like
NOTICE - When a character inadvertantly sees, hears, feels or otherwise senses something they were not actively searching for. This is dependent on raw sensory ability and situational awareness.
SEARCH - When a character actively looks, listens, feels or otherwise searches for a particular thing consciously. This is a combination of sensory ability and knowledge/experience (knowing what clues may be present to help find the sought for)
