On the “Personal details and settings” page, you can configure three personal settings:

• Allow saving my search history: When enabled, your search history is retained between sessions.
• Use my search history for the search suggestions: When enabled, the system uses your search history to provide recent search suggestions.
• Automatically extend my session: When enabled, your session is automatically extended without prompting you to do so.

By default, all of these settings are deactivated.
