This is the first time i've come up against this one, i have cleared all internet history, deleted all temporary files but google still has all the things i've searched for (not saying its anything saucy

) but its getting annoying, i'm sure there is an option somewhere to get rid of these i just can't find it, its something to do with the predictive text but i can't find the option to clear it, please help, its driving me up the wall
