I'm seeing some funny behavior too in real-time search. The odd part is, I'll see a very brief wave of visits to a single page, all with varying search terms. Then a little bit later I'll see another similar wave, this time to another page with different search terms. Definitely feels like a test, but it could also be coincidence.
