8. The system of claim 1 wherein calculating the search rank results further comprises ranking the first and second documents according to a scoring function (score) that is determined according to at least: the at least one of the click distances associated with each of the first and second documents (CD), a weighted term frequency (wtf), a weighted document length (wdl), an average weighted document length (avwdl), a number of documents on the network (N); a number of documents containing a query term (n), a weight of a query-independent component (W cd ), a weight of the click distance (b cd ), a weight of a URL depth (b ud ), the URL depth (UD), a click distance saturation constant (K cd ) and other constant (k 1 ,b).
