Stop saving your search history
By default, your device keeps the last 20 search results that you visit for quick reference and reuse. If you don't want to
save your search results, you can turn off this feature.
In the BlackBerry Device Search app, tap > Settings.
Turn off the Save search history switch.
Tip: To delete an individual search result, swipe left or right on the result. To clear all of your search history permanently,
tap > Settings > Clear search history.
