If you're enraged over relocating a "+" prefix to a double quoted word, then you might not want to use a post-2005 version of Microsoft Office...
I could be wrong, but it seems to work for me.
Imagine the name Dan Northern. I search using (without square brackets)
["Dan Northern"]
I don't ever want, for that search, to see any results like:
["Dan's Northern"]
But I do, sometimes. (Using different names, which I'm not giving here to protect a friend who actually does need protection.)
But Google has a handy feedback form, and I report it when it happens, and sometimes it seems to make a difference.
I would freaking love to see some of that feedback.
