Often. It seems sometimes I get selected for an A/B test where they just ignore parts of my query even if I use doublequotes and verbatim option.
Also this becoming standard means Google have taken a(nother) step backwards since 2009.
Which might be a good thing in the long run. It means competition has even better chances. :-)
The one thing I really miss is insta-results for things like 'population of USA'. On the other hand, I think Google was going a bit too far with that and started giving insta-results that at times were subjective, or even simply wrong.
I've been using findx.com as my default search engine lately. I still use the find on google option often though, since it's not nearly as good as DDG (There is a search on DDG option next to the Google one as well).
