Hi, in this blog I am going to describe the process to initiate site re-indexing in Office 365 SharePoint sites. It helps to initiate search crawl and enables the site to be consider edduring the next search crawl. Let's get to the steps.
On the site, click Settings > Site Settings.
Once we are at site settings, click search and offline availability under Search group.
In the search and offline availability section, click Reindex site button.
This will show anwarning popup where we have to confirm the site re-indexing.
Click on Reindex site again to confirm. The content will be re-indexed during the next scheduled search crawl.
Thanks .
