Explanation
Administrators can activate search results in Knowledge Advanced so that agents, when searching Knowledge Advanced from an incident, can see only articles relevant to the areas the agents support. The filtering equates user groups with web roles and service level agreements; however, you can only tag articles with user groups.
You configure content visibility for user groups and content processing authentication for external collections using either the Collection Wizard or Collection Form under Manage Collections.

Explanation
Answer variables are predefined shortcuts for entering information into an answer instead of a long string of text. When an answer displays on the customer portal, the variable is replaced with whatever value was specified by your administrator.
Variables are also helpful to use for information that may change. When your administrator changes the value of the variable, all answers containing that variable will also change. Contact your administrator for a list of variables defined for your application. For example, if your administrator added a variable for a support email address at your organization called "contact," you could insert the variable for the email address in the answer, such as $contact. If the email address changes, all answers containing the contact variable are updated.
