They would need to check a locked chest, and the door to the next room separately though.
The thing that made me develop this technique was when I succeeded on my find traps roll on a door, then sprung a trap when I went to pick it. "You didn't say you searched the lock". After about an hour of bogging the game down by searching literally everything the DM mentioned for traps, I encountered a crazed gnome that was humming a song to himself. I told the DM that I was searching the gnome for traps. DM was getting annoyed. Then I told him I was searching the song for traps. I wasn't welcome back next session, lol.
