Fess provides 2 user interfaces:
Search form and results
Administration (used to configure and manage Fess)
Both interfaces are accessible via a web browser.
This is the primary UI which allows end users to run search queries and view results. Users will type in their query and click Search to view the results.
This UI is only used by administrators to configure and manage Fess. Administrators will be prompted to login before they can access the rest of the Administration interface.
