You can protect or block a search to prevent any user in your domain from modifying it. This is useful when, for example, you create a particularly complex search and you don't want to risk accidentally modifying it.
You can also block searches from the Favorite searches and Search history lists.
Unblock a search
Blocked search are indicated with a lock icon in the Favorite searches and Search history lists. Blocked searches can be unblocked in these areas by clicking the lock icon.
Be aware that even though the process of blocking a search is performed automatically, the process of unblocking requires an in-between step. For a search to be unblocked it is necessary to close it after clicking the lock icon and then reopen it from the Favorite searches or Search history sections.
