This is an interesting observation. I have just noticed the same on my own site. Only a couple of days ago I used to rank #5 for the term "buy widgets online" but today the site has completely disappeared for this search. When I look in GWT I also cannot see the keywords "buy" and "online" although they are prominent words on the site. "Widgets" is still top of the list though.
