Microsoft Search in SharePoint is the modern search experience in SharePoint Online. SharePoint Online also offers a classic search experience. As a search administrator, you can’t turn either of these search experiences on or off. They're both on by default. Which search experience your users get depends on where they search from:
Users get the Microsoft Search box on the SharePoint start page, hub sites, communication sites, and modern team sites.
Users get the classic search box on publishing sites, classic team sites, and in the SharePoint Search Center.
To get your organization going with Microsoft Search in SharePoint, take the steps in the following sections.
Prepare for Microsoft Search in SharePoint
Users can only find SharePoint content that's been indexed. Microsoft Search and classic search share the same index for SharePoint content, which is crawled and indexed automatically.
Teach your users to search from the SharePoint start page instead of from the classic Search Center. Consider hiding your classic Search Center from users.
Learn about Microsoft Search including where users can search, the answers and results they'll see, and how you can tailor the search experience for your organization.
