Differences between the classic and modern search experiences in SharePoint Online

SharePoint Online has both a classic and a modern search experience. Both search experiences use the same search index to find results.

As a search administrator, you can’t turn off neither classic nor modern search. Users get the classic search experience on publishing sites, classic team sites, and in the Search Center. Users get the modern search experience on the SharePoint home page, hub sites, communication sites, and modern team sites.

The most visible difference is that modern search is personal and the results you see are different from what other people see, even when you search for the same words. You'll see results before you start typing, and the results update as you type. Learn more about the modern search experience​.

​ Another difference is that search administrators can customize the classic search experience, but only impact some aspects of the modern search experience. See Overview of search to learn about the main areas where you can customize and impact the search experience and make sure that search is performing the way you want.​ ​

Unlike the classic search results page, the modern search results page isn’t built with web parts. You can’t customize the modern search results page or create additional search results pages.

There aren't separate search settings for the modern search experience. Instead certain of the classic search settings also apply to the modern search experience:

  • The search schema determines how content is collected in and retrieved from the search index. Because both search experiences use the same search index to find search results, any changes you make to the search schema, apply to both experiences. The following search schema settings don’t affect the modern search experience:
    • Sortable
    • Refinable
    • Company name extraction
  • The modern search experience only shows results from the default result source. If you change the default result source, both search experiences are impacted.
  • If you temporarily remove a search result, the result is removed in both search experiences.
  • When you create a promoted result at the tenant level, users can see it in both search experiences. In the modern search experience, users only see promoted results on the All tab on the search results page and only when they search across all of SharePoint.
