Google's "Zeitgeist 2010: How the World Searched" report, released Thursday, said other rapidly rising search terms this year included Justin Bieber, Nicki Minaj, Katy Perry, iPad, Twitter and Facebook.
Rounding out the Top 10 were cellphone ringtone site Myxer and gaming sites Gamester and Friv.
Meanwhile, the report said search terms falling in prominence from last year include swine flu, "Twilight" series book and film title "New Moon" and singer Susan Boyle.
Google said the list-topper for its "strangest searches" of the year was the question: "Can a horse have OCD?"
