Found this Google search string in my stats. What does it mean?

While checking my stats for today, I found the following search string under Referring Links:

http://www.google.com/url?sa=t&source=web&ct=res&cd=4&url=http%3a%2f%2fwww.example.com%2fMy_Topic.html&ei=lubrsrpahzt6sqolg7mqdq&rct=j&q=A+Question+That+My+Topic+Page+Addressed&usg=afqjcnf7rj-iclzgxpqullj-msnsgaknpw&sig2=pmc4jxg891wtjysnv6ddpa

I've substituted the real URL with example.com/My_Topic.html and the search query with A Question That My Topic Page Addressed.

I don't recall seeing this kind of search string before, although I seem to recall some here talking about Google tracking searchers from time to time.

Any ideas as to what this is?

Here's the most recent discussion about the new referer strings:

I think that thread touches on at least most of the elements in your referer string.
