Ask HN: Has Google search quality abruptly went down *in the last week*?

I just realized that I started rephrasing queries and extensively using quotes in past few days, or maybe a week. Very sudden and noticeable change in the search quality. Simple queries that worked now return irrelevant stuff in first page. Also the word matching appears to have gone "fuzzy" - first few hits routinely do not include all or exact words from the query, which is not how it was before.

Has anyone noticed something similar? Or am I seeing things?
