After you’ve made changes to managed metadata or the search schema you may wish to re-crawl your content sooner than the next scheduled crawl. You can do this across all site collections (on-prem/server), one site at a time (O365 or on-prem) or individual lists and libraries (O365 or on-prem).
O365/SharePoint Online
In O365, you can’t trigger a full crawl of all sites using central admin like we can on-prem. But some use scripts to achieve the same effect. In O365, content is continually crawled instead of scheduled like on-prem. You can, however, reindex individual sites, lists and libraries on-demand as noted in the next section:
Individual sites, lists and libraries (O365 and on-prem)
To crawl a single site/library/list by using site or library settings then reindex site/library/list.
Sites
- Go to site settings
- Under “Search,” click “Search and Offline Availability”
- Click “Reindex site”
Lists/Libraries
- Go to list/library settings
- Go to “advanced settings”
- “Reindex List” or “Reindex Document Library”
All collections (On-prem/SharePoint Server)
And if you’re on-prem/server, you can crawl all site collections and their content by following these steps:
- Go to central admin
- Click “manage service applications”
- Click “Search service application”
- Under “crawling” click “Content Sources”
- Click “start all crawls”
You could also just crawl one content source by using the dropdown and selecting full or incremental.
