I've been looking through the forums to see if this has been posted and I don't find it so I'm guessing either no one searches (through the search widget ) or it's just my phone BUT, ever since miui divided the address bar on the browser, when I search from the Search Widget, instead of getting a result, the search button opens the browser and goes to Google but does nothing. I did a full install from 2.6.16 and updated to 2.6.22 so I don't know why this is happening. To replicate, set the widget on your home screen, type something to search, click on the go button and see what happens. For me, it opens the browser, goes to google and that's it. Sorry, I forgot to add that I'm on a SGS II... don't know if it is relevant.
