Yes, it goes the same for me:
my site was number one for
programming outsourcing and now is just not within the search results. Using allintext:programming outsourcing, I get it "back" on 1st place.
On the other hand, while I was ranking 1st for the above keyword, I had no ranking for
programming outsourcing services. After the last Google update, I rank 1st for
programming outsourcing services. Of course, it's a far less important keyword :-(
Based not only on the above example, I noticed that Google is trying to extend multi-word keywords as much as possible. So if your page contains word1 + word2 + word3, for Google your site is not relevant for word1 + word2, but only for the full string. Of course, this was valid before, too, but it looks like Google increased its importance.
So maybe Google is just trying to narrow the search results?
