How to delete "search history" in Xbox Music Search Collection?
My phone is Lumia 920 and the OS is Windows Phone 8.1 Dev Preview. All Apps including Xbox Music are updated.

Things I did:
1. Deleted the search history in Bing Search
2. Deleted I.E History
3. Deleted Temporary Files
4. Deleted Play History and New History in "Stop+Clear" App

- None of them work
