A profile is a collection of data (URLs/documents) to be searched, plus the settings that control that search; a profile must be created and walked before searches can occur.
On the Profiles page,
a default profile name and
data directory will be filled in for you to create. You may change either
of these if desired, then hit the Create Profile
button.
A new profile
will be created but a site walk/index will not be started yet.
You are then presented with the main walk settings page. The
Base URL
will be automatically filled in with the name (or IP address)
of your web server. If you wish to walk a different site you may
change the Base URL
at this point.
