Here is an example looping over all the terms in an index;
require 'rubygems'
require 'ferret'
def print_all_terms(index)
index.field_infos.each do |field_info|
field = field_info.name
index.reader.terms(field).each {|term, freq| puts "#{field}:#{term}"}
end
end
index = Ferret::I.new
[
{:one => 'one', :two => 'one two three'},
{:three => 'some knew terms', :four => 'the fourth field'}
].each {|doc| index << doc}
print_all_terms(index)
Hope that helps.
Dave
