NAME

ROADS::Rank - A class to rank WHOIS++ search results

SYNOPSIS

  use ROADS::Rank;
  # @results are the results of a WHOIS++ query done already
  @ranked_results = rank($query, @results);

DESCRIPTION

This class defines a mechanism for sorting the results of a WHOIS++ search according to the number of occurrences of the search terms in the resulting templates.

METHODS

rank( query, @results );

This method takes an array of WHOIS++ template handles results, and the original search terms query which gave rise to them. It sorts the handles according to the frequency of the search terms in the templates which they point to, and returns the sorted list.

BUGS

We probably don't cope very well with some of the possible permutations of search terms and punctuation. Perhaps we should strip them down to just alphanumerics before doing the comparison ?
