Microsoft are adding a new option in Microsoft Search that will allow you to view and manage your personal query history.
How will this affect you and your organisation?
With personal query history, you will see recent search queries across SharePoint Online and Outlook (web) as you begin typing in the search box.
This will make it easier to return to recently accessed insights and information. There is no need to bookmark or memorise your frequent queries.
This feature is managed and downloaded though the Microsoft 365 My Account settings.

A new option in the My Account privacy controls will enable you to manage your personal query history, such as downloading history for future references
