Google is adding a Personal search tab
Under the More tab on the search results tab Google is adding a Personal tab. Selecting it searches your personal information stored in Google.
Selecting Personal searches for matching data in your Calendar, Gmail, and Photos. It doesn’t appear to search Google Drive for content though.
The Personal tab is only showing for personal accounts right now, and there isn’t any word on when (or if) it will roll out for G Suite customers.
