Ranking and Normalization

IB supports many models of sorting result sets:

By Record Key
By order as indexed
By an external sort
By Score
By Adjuncted Score
By number of different term matches
By Date (either forward or reverse)
By Category
By Newsrank (a heuristic that combines "score" with a function of chonology). The idea behind "Newsrank" is that newer stories are more significant than older ones.
