On the privacy page, they list "What we log", along with this statement...
We don't correlate or combine your information from the temporary or permanent logs with any other data that Google might have about your use of other services, such as data from Web Search and data from advertising on the Google content network.
I fully understand that they could use a DNS service to extract all sorts of information if they did correlate with search data. Without that correlation, what information could they be extracting? And they don't in fact seem to be saving any information that could be used to link logged information to search information at some future date.
I'm not trying to say that there shouldn't be a concern, btw... just trying to understand what it is.
