but its functionality changed around June 2008

Didn't know about that.

So if the Sponsored Links search is unrelated to the keywords and shows just the ads that have the query words

That would make sense. But in my case, I search for the same exact keyword that I target.

The phrase is both in the ad title and in the keyword list.

I understand the idea of matching ads by ad text, as if ads are documents. And that's actually a pretty good idea.

But unfortunately, it's messes up my tracking.

Fortunately, there aren't that many people running queries on the sponsored links search. (yet?)
