Specify how long should Funnelback keep the session since the last visit of the search user.
Can be set in: profile.cfg, collection.cfg
This setting controls the session timeout for the search session and history features.
The timeout is the time since the last visit of the search user to the Funnelback server. If the user returns to the Funnelback servers past the configured value, its session will be discarded and a new one will be created, generating a new user identifier.
The timeout is expressed in seconds.
