I am creating a metro style app and I’ve implemented the search contract with suggestions. When a suggestion is picked, it remains stored for other searches even if it doesn’t exist anymore(like a web text field cache). How can I erase these suggestions?
(EDIT: and if it isn’t possible to clean it programmatically how can I erase that suggestions manually, because they filled all the space in the search-box suggestion area.)

As you can see even if I don’t search for anything the suggestions are there.
I figured that out:
Settings Charm > Change PC Settings (Windows 8 metro style control panel)) > Search > Erase History(i am not sure that is is the proper naming in english for the path i have windows in another language).
