I have no inside information on this, but it's based on my usage of Google recently. I believe Google seem to be guessing at people's intended search query rather than performing the query based on the actual terms.
This is probably great for most people as Google's own data shows that most people do indeed search the same things at the same time, so guessing intention (especially with relation to current affairs and the queries of others) is probably a winning strategy for giving most people what they want - even if their search terms were a bit junk.
The down side is that the ability to hone results by tweaking or rearranging ones search terms goes largely ignored. Previously one could peel away layers of results with such meddling, now it seems there will usually be some word or name in the search query which Google will be affectionate towards, and the results are unmovable from that.

I've read that google uses "Machine Learning" for their search results which I interpret to be exactly as you say they provide a stereotyped result based on what they think you are searching for (possibly optimized either for what is inevitably clicked on or for ad revenue), instead of actually matching terms.
What this means is that search results may be more accurate in some statistical way, like more people click on the top result, but it also pumps up the number of edge cases where it guesses wrong, while simultaneously making it impossible to tell where the results went wrong because you can't understand how they were generated (compared to eg keywors search where good or bad, the reason you got a result is obvious)
