Oh, right, forgot about this one....if you're nitpicky, Saguru does not just mean "To search" (the -ru ending means it's an unconjugated verb, so it isn't "searching") it means "to investigate" or "to probe" (ha ha)

Now if it was SaGAru, it'd be some butchered form of "to search" (which is "sagasu", by the way).

Japanese grammar whore, ahoy!
