Nothing is more fun than guessing what arbitrary macguffin the DM has in mind. Or tirelessly asking if you see anything in this corner or that corner, or over there, or under the desk, or behind the tapestry.
In my experience, it pays to have a conversation with the DM out of game time to tell them that they should probably describe whatever there is to see in the room.
If there's no time pressure and no traps, there's no reason you can't just say "I rummage through every shelf in NPCs personal library in search of the book!" or something.
