Google Search for “Apple quietly”

Edit: Apparently "quietly" in some search strings (Not just "Apple", "Insurance", for example, behaves similarly) removes the top yellow ad box, as well as the side map. I'm not sure there's any significance to this, as I think it's the result of the word having a tendency to bring up news results ("quietly" probably appears more in news articles than in generic content), which seem to take higher priority than the ad box/side info. It doesn't work, for example, in "Plumber" vs "Plumber quietly".
Edit: Sorry. You should notice that the top ads and the crap on the right is missing.
But if I search for "life insurance quietly" - https://www.google.co.uk/search?q=life+insurance+quietly - ADS!
This is a total non-story, caused by not understanding keyword matching algorithms. If you add words to a query, it turns out your query becomes less related to potential keywords that have been targeted for adverts, and this drop in relevance might be enough to cross the threshold where adverts are shown at all
