SharePoint Online search administration overview
SharePoint Online has both a classic and a modern search experience. As a SharePoint Online administrator, you can customize and impact the search experiences for users. Learn about the differences between the classic and modern search experiences. You can define searchable managed properties in the search schema, identify high-quality pages to improve relevance, manage query rules and result sources, and remove individual results. You can also evaluate any changes by viewing reports about usage and search.
The changes you make from the search administration page are valid for the whole tenant, but you can also customize search on site collection level and on site level.
How to get to the search administration page
Sign in to Office 365 as a global admin or SharePoint admin.
Select the app launcher icon in the upper-left and choose Admin to open the Office 365 admin center. (If you don't see the Admin tile, you don't have Office 365 administrator permissions in your organization.)
In the left pane, choose Admin centers > SharePoint.
Choose search in the left pane.
