Activate SharePoint Global Search on Hub sites

The Hub sites that are connected on SharePoint (hubify), by default will have the search made on the particular site that the users connects. Making the search on those SharePoint sites to be global can make the life easier of your employees to find documents on the Intranet. On this article, we’ll provide a PowerShell script that makes all the sites of that particular Hub to have the Search globally activated.

For now, to activate this feature you need to run this PowerShell script, however, Microsoft will provide a way to set this setting using the UI later this year. It’s possible they provide this option per site. If you don’t have permissions, it’ll show the sites that you didn’t have permissions to activate this feature. You can then send them the PowerShell to activate on that particular site. You can check that script on the next link.

Conclusion

Regardless of the site where you’re user is connected, they will have access to all documents stored on intranet on the search area and avoid to go on a specific site to search a document.
