Base Claim:
1. A computer-implemented method for presenting a ranking of search results, comprising: providing an index to a plurality of documents including: a main index associating with each of the documents a frequency of one or more terms being included in each of the documents; an anchor text index associating with each of the documents an anchor text frequency of the one or more terms being included in anchor text in a source document referencing each of the documents; receiving a query including at least one query term; applying the query to the index to yield results of the query identifying one or more of the documents that include the at least one query term; applying a scoring function to generate a score for each of the one or more documents included in the results of the query, wherein the scoring function (score) includes one of: score = ∑ ( wtf B + wtf Anchor B Anchor ) ⁢ ( k 1 + 1 ) k 1 ⁡ ( ( 1 - b ) + b ⁢ w ⁢ ⅆ l avw ⁢ ⅆ l ) + ( wtf + wtf Anchor ) × log ⁡ ( N n ) ; ⁢ and score = ∑ ( wtf B + wtf Anchor B Anchor ) ⁢ ( k 1 + 1 ) k 1 + ( wtf B + wtf Anchor B Anchor ) × log ⁡ ( N n ) , where: wtf is a weighted term frequency applying a weight to a frequency with which a given query term is included in the document; wtf Anchor is a weighted term frequency applying a weight to a frequency with which the given query term is included in anchor text referencing the document; k 1 is a constant; b is a constant; wdl is a weighted document length applying a weight to a length of the document being scored; avwdl is an average weighted document length of all documents being scored; N is the number of documents on the network; and n is the number of documents including at least one appearance of a given query term; and generating an output of the ranked results of the query to be displayed to a user.

Claim 8:
8. The computer-implemented method of claim 1 , wherein a strength of the length normalization provided by B Anchor is adjusted by choosing a different constant value associated with B Anchor .
