Ask HN: Is it just me or did Google search recently get a lot worse?

Past few days(weeks?) I find myself more and more frustrated with google search. It seems to frequently omit the most important keywords I'm typing. I constantly have to click "Must include 'Keyword'", because more than half the links on the first page miss it, even if it's the first one out of 3 words in my query.

I'm not the kind of person who thinks about search quality, this is the first time in my life I have ever noticed it being frustrating.
