Even quotes don't actually work. I've witnessed google query rewrite even with full quotes. I've also seen other posts on HN from others who've had this happen to them.
Quotes do work. They really, really do. Every time I look into a complaint about this, I find that the text really is on the page. It just might not be readily visible. Twitter link is in my bio here. If you ever get an example where you find quotes don't seem to be working, do pass it on.
