Acquia Content Hub uses a discovery mechanism to understand what content is available for import into a subscriber website.
To reach the Content Discovery page:
In the left menu, Content Discovery is highlighted by default. You may also choose Saved Filters to view any existing filters on your subscriber website.
The Content Discovery page body displays a list of filters to narrow down the available content.
Use these filters to create new filters.
The list of content displays below the filters. The content information imports directly from the content on the publishing website, and generally includes the items used for filtering content.
