Your customer has built a mature knowledge base for internal and external audiences. What feature would help agents identify visible articles?

The feature that would help agents identify visible articles is "Search as User." This functionality allows agents to conduct searches from the perspective of the end users, thereby revealing which articles would actually be accessible to them based on their roles and permissions.

By using "Search as User," agents can understand the visibility and relevance of knowledge base articles, ensuring that they are directing users to appropriate resources. This is particularly important in environments where the audience may include both internal staff and external clients, as different articles may be geared towards different groups depending on their access levels.

In contrast, features like "Internal/External Highlighting" and "Show User Viewable" might suggest visibility to certain content but do not fully empower agents to experience or validate the end-user experience as it pertains to searching. "User Only View" could imply a filtered view, but it doesn't inherently contribute to the process of searching for articles in the same way that “Search as User” allows agents to evaluate the actual search experience from the user's perspective.
