Which feature helps in filtering content based on specific criteria in Sitecore?

Filtering content based on specific criteria is primarily done through the use of tags and categories in Sitecore. Tags and categories allow developers and content managers to organize and classify content effectively. This classification enables users to quickly retrieve and manage content based on common attributes or themes. By assigning specific tags to pieces of content, users can create dynamic presentations of content that can be filtered based on these tags, allowing for more targeted content delivery and discovery.

In contrast, content workflows focus on the process of content creation and approval, ensuring that content goes through necessary stages before being published. Publishing schedules are concerned with the timing of when content becomes live or is taken offline, while access controls manage user permissions and restrictions for viewing or editing content. While these features are essential for content management, they do not inherently provide the means to filter content based on criteria like tags and categories do.
