Microsoft is improving the way they show user’s private OneDrive content in Microsoft Search in SharePoint

During November we will make changes to the default SharePoint Online search experience to make content from the user’s own OneDrive for Business more clearly separated in the search results. With this change, the results will be clearly labeled as ‘Results from your OneDrive’.

An important reason for this change, is feedback from customers that returning search results from private content mixed with all other content may be confusing in an enterprise search result. Also, a clearer interface delineation aids users to find the content they are looking for faster. Private content is content that hasn’t been shared with anyone else from the user’s own OneDrive.

[How does this affect me?]
Starting November 26, in addition to the UX change, we will change the default scope for user queries issued via the Microsoft SharePoint CSOM and REST search API, in which private, non-shared results are filtered out of the tenant-wide search experience. As a reminder, users will only see results they have access to, including files in SharePoint and OneDrive that are shared with others.

[What do I need to do to prepare for this change?]
If your organization uses the SharePoint Online search API to power a search experience, and users expect to receive results from SharePoint and OneDrive for Business, including their private OneDrive for Business content, review the Additional Information to learn more.
