Agree. I've worked on search for about 10 years. One of the most frustrating things is that no matter what your view point you can always find one or two queries to justify it. Individual queries can be a useful debugging tool, but it's no way to try to assess general search quality. That can only be done by looking at user behaviour over a huge sample set (and over time).
