Just got the Tmobile mytouch 4g slide and was wondering if this is possible?

On my Droid 2, I can slide the keyboard and when I unlock the phone, at the homescreen, I don't have to do anything but start typing and google search pops up (and I know you can have google search to set contacts, web, calendar etc and those options)...but what I am asking is...on my Tmobile mytouch 4g slide, I cant seem to do that, when i unlock the phone and start typing on the home screen, nothing happens...can't seem to find any settings either to activate this option (which i do not believe i needed to do anyways on my Droid 2).

Would love any thoughts as this was a very useful and quick feature since I'm always typing right away to search things whether its contacts or on google etc.

Thanks!!!
