Redoing search from results page
So I had heard that there was a keyword to get Google Now to redo a search from the results page if it got the voice recognition wrong the first time. I couldn't find it after multiple searches, so I decided to try some variation of "Google" or "ok Google" or something in some blind attempt to stumble on it. Apparently, the keyword is none of these. Finally, something possessed me to say "giggle"...and it worked. Was everyone else aware of this and I am just an idiot, or what?
EDIT: So now "ok Google" seems to be working, which was my original assumption that out was just mishearing "Google". Yet "Google" definitely wasn't working for retry at first, though it was working to initiate. Weird... (Maybe I am crazy!)
