After moving ticket, be able to search by old key

When moving an issue from one project to another a new key is created for the issue based on the new project. If you look at the changes history for the issue it will show the ticket going from the old key to the new key.

Please add the fucntionality of being able to search for the ticket by the new and old key. Currently you are only able to search for the ticket by the new key. Since the old key is in the change history, please allow to do a ticket search by the old key.
