Huh? This is not the case for me at all, just tested. Not doubting your experience, but it's weird that such a fundamental aspect of search (not even targettable to anything) would differ from user to user.
Just to clarify, we were discussing gmail search and not the main web search. I just tested again, if I search for 1-1/2" (with the quote mark) I get zero results.
This is google-for-business or whatever they call it now.
