How do I clear the search history in the google search bar in my Nokia 6210 Navigator?

[ChildOfBo(re)dom]

Im wondering how I go about clearing the search history in the Google search engine in my Nokia 6210 Navigator. I dont know if Ive explained it properly but its like the google search engine on the PC where you type something in and it suggests common searches. Only this suggests what Ive already looked at. I want to clear this so nothing is suggested while Im typing in a new search. Also, some of the searches were personal and Id rather people didnt see them. Clearing the browsing history and clearing privacy data dont do anything. Ive also just updated my phone and that hasnt helped. Help is appreciated! Thanks
