So what? It's a dream.
This Google Search analogy doesn't work anyway. If I were to do a google search in a dream, the results I got wouldn't be based on anything except my own subconscious. My brain isn't tapped into the real google, so I wouldn't get accurate results.
BUT, my brain DOES know how the dreamboxes are supposed to work, so if I had one in my dream, it would work just fine because my subconscious already knows what to do with it.
