Hi!

Suppose I have many articles in a database and I want to know how many  
times each search term appears in each one of them. Where do I start?

Thank you very much!

David

Here is an example;

require ‘rubygems’  
require ‘ferret’

index = Ferret::I.new  
index \<\< {:content =\> ‘one two three’}  
index \<\< {:content =\> ‘no 3 here’}  
index \<\< {:content =\> ‘three three three’}

index.reader.term\_docs\_for(:content, ‘three’).each do |doc, freq|  
puts “three appeared #{freq} times in document #{doc}”  
end
