SharePoint Hub sites search

Hello awesome SharePoint community! 

I have a question regarding SharePoint Online hub sites and Search.

My scenario:

I have a Hub site and three sites associated with that hub site. Other than that i have multiple sites with no hub association.

When I use Search across sites it first presents the content inside these three hub sites but when I press Show more results I get search results from the whole Organization.

Is there any way to stop that? I only want the Search within the Hub sites and not the whole organization.

Thank you in advance!

Best regards, Sammy
