Increasingly, I’m using Google Docs with collaborators. Yesterday, one of them pointed out the new “Research” search tab within Google Docs. (Tools->Research). I’m a bit surprised that your searches don’t show up on your collaborators’ screen. I’m particularly surprised that sharing searches doesn’t seem possible.
Google Docs' new 'Research' tab promotes search within Google Docs.
Apparently, it is pretty new. More at the Google Docs blog.
