I hear this a lot, but it I haven't personally noticed any real problems with quoted search (other than the occasional difficulty actually finding the content on the resultant webpages).
I have noticed a general decline in search quality over the last couple of years, but nothing specific to quotes.
I realise I'm not saying anything particularly useful with this comment, but I just thought I'd add another datapoint.
Edit: Thinking more, my biggest issue is when the quoted text occurs in the "recommended similar posts" section of a page (particularly common with reddit). That section gets re-rendered on each view, so it probably won't be there once I click the result.
