Regardless of the query string quality, it would be really interesting if these results could be compared somehow with the results from 8 years ago.

When Google was not evil yet, their search engine was like magic, it just knew what you were searching for. Sure, time makes forget about problems, but there is a reason why their search engine allowed to become the behemoth they are today.

I love that methodology, I wish we scaled it to get an accurate leaderboard.
