They explicitly say they're taking search terms from Google (etc)  
requests.  All of those URLs contain a ?: that's how the parameters  
are passed.   For example,

http://www.google.com/search?client=safari&rls=en-gb&q=roland+perry&ie=UTF-8&oe=UTF-8

A cache would be unwise to try to cache searches and respond with  
cached search results: the hit-rate would be low, the implications for  
users quite unpleasant.  But Phorm explicitly have to catch search  
terms, as that's a large part of their proposition.
